Qayb Muhiim ah oo ka mid ah Qalabka Idaacadda

 

Waa kuwan dhowr sababood oo filtarrada hoose ee RF ay lagama maarmaan u yihiin warshadaha baahinta raadiyaha:

 

  • Harmonics iyo qiiqa wasakhaysan lama ilaalin karo, waxayna saamayn doonaan idaacadaha ku jira xadhkaha raadiyaha ee kala duwan waxayna hoos u dhigi doonaan tayada barnaamijyada raadiyaha taasina waa qiimaha ugu muhiimsan ee shaandhada hoose ee coaxial ee xarunta raadiyaha.

 

  • Haddii aadan isticmaalin shaandhada hoose ee RF ee xirfadleyda ah, waxay u badan tahay in lagu ciqaabo waaxda maaraynta raadiyaha maxalliga ah (sida FCC) abuurista faragelin ballaaran oo raadiyaha, tusaale ahaan, tirooyinka iswaafajinta aan la rabin iyo qiiqa xunxun ee ay dhaliso FM-kaaga iyo gudbiyaha TV-ga

 

  • Gudbiyeyaasha raadiyaha waxay adeegsadaan filtarrada kaadhka hooseeya ee soo noqnoqda awoodda sare si ay uga hortagaan qiiqa iswaafajinta ee laga yaabo inay farageliyaan isgaarsiinta kale.

 

  • Si loo xakameeyo is-waafajinta gudbinta idaacada FM: Gudbiyeyaasha FM waxay inta badan soo saaraan isku-dhafan - tiro badan oo soo noqnoqoshada gudbinta. Qaarkood waxay keenaan faragalin VHF-TV iyo UHF-TV soo dhawaynta iyo soo dhawaynta raadiyaha gacanta. Taxanahan shaandhada hoose ee awoodda sare leh waxay dhex maraan dhammaan guutooyinka soo noqnoqda ee FM-ka oo leh khasaare hoose waxayna bixiyaan wax badan oo xakamayn ah.

 

 

Ka soo iibso Shaandheynta RF Harmonics Broadcast FMUSER

 

Qiimaha ugu weyn ee RF Harmonics filter waa in lagu caawiyo idaacadaha inay doortaan calaamadaha loo baahan yahay si loo isticmaalo. Gaar ahaan idaacadaha waaweyn, sidii dhageystayaasha loogu heli lahaa barnaamijyo tayo sare leh oo aan la ciqaabin maamulka idaacadaha maxalliga ah ayaa shardi u ah in sare loo qaado tartanka facooda idaacadaha iyo in sare loo qaado garaadka idaacadaha.

 

FMUSER waxay bixisaa filtarrada harmonic sida 20kW FM filtar hooseeya Heerarka awoodda gudbinta ilaa 20 kW. Naqshad gaar ah ayaa bixisa 45 dB ama diidmo ka weyn laga bilaabo labaad ilaa tobnaad harmonic iyo wixii ka baxsan. Tani waxay soo saartaa filtarrada leh dhererka guud ee 30% ilaa 50% ka gaaban filtarrada harmonic FM ee caadiga ah. 

 

Waxaan haynaa filtarrada RF ugu fiican ee iibka ah, iibso filtarrada RF awoodaas oo u dhaxaysa 500W ilaa 1000W FMUSER! Gaar ahaan, waxay yihiin 20kW FM filtar hoose oo iib ah (LPF) iyo 10kW VHF filtarrada hoose ee iibka (LPF), 10kW VHF bandstop filter oo iib ah (BSF), 350W UHF filter bandpass dhijitaalka ah oo iib ahiyo mid ka mid ah qalabkayaga idaacadaha iibka sareeyo - filtarrada bandpass FM iib ah.

 

Waxaa laga yaabaa inaad hesho dhammaan waxaad u baahan tahay haddii aad sii wado sahaminta, waanu haysanaa filtarrada bandpass FM Awooddaas oo u dhaxaysa 500W ilaa 1kW, gaar ahaan, waa 500W, 1500W, 3000W, 5000W, 10000W filtarrada bandpass FM kuwaasoo si gaar ah loogu talagalay idaacadaha FM-ta. Ka sokow, habaynta ayaa diyaar u ah filtarrada harmonics, dhammaan waxay wataan kharash miisaaniyadeed iyo tayo la yaab leh, na weydiiso taageero, dhammaanteen waxaan nahay dhego!

 

Sida mid ka mid ah kulannada baahinta ugu muhiimsan ee idaacadaha FM/TV, shaandhada daloolka RF Waxay lagama maarmaan u tahay sida isku-darka FM / UHF / VHF, gudbiyaha baahinta raadiyaha, anteenada gudbinta, iyo qalabka kale ee idaacadaha la midka ah. Ma aha buunbuunin in la yiraahdo iyada oo ah sheyga udub-dhexaadka ah ee alaabta RF, filtarrada ayaa runtii aad uga muhiimsan shirarka kale ee aan caadiga ahayn ee ku-celiyeyaasha iyo saldhigyada saldhigga.

 

Weli, shaandhada RF, tusaale ahaan, shaandhada RF-ka ee hooseeya, waa aalad lagama maarmaan u ah dhinaca gudbinta ee xarunta baahinta si loo xakameeyo is-waafajinta uu dhaliyo gudbiyaha. Tani waa sababta oo ah hawlwadeenada nidaamka RF adduunka oo dhan waxay adeegsadaan soo noqnoqoshooyin kala duwan, sidaa darteed waxaa jira calaamado badan oo jahwareersan oo hawada ku socda, qaarkood waxaa loogu talagalay telefishinka, militariga, kuwa kale waxaa loogu talagalay cilmi baarista cimilada iyo ujeedooyin kale.

Qaybta Xigta waa Shaandheynta RF Harmonics-ka ugu Fiican ee Iibka | Skip

 

Waxa dhibaya dhammaan injineerada RF waa in qiiqa iswaafajinta iyo wasakhda ah aan la iska ilaalin karin. Hawl-wadeennada idaacadaha, aad bay muhiim u tahay in la fahmo waxa is-waafajinta iyo qiiqa qiiqa ah ay yihiin, ama sida ay u abuurmaan iyo sida loo yareeyo saamayntooda.

 

Isla mar ahaantaana, waxa kale oo faa'iido leh in la xakameeyo tayada barnaamijyada idaacadaha, FMUSER kooxda farsamada ee RF ee xirfadlayaasha ah waxay noo sharaxeen qaar ka mid ah aqoonta aragtida ee ku saabsan iswaafajinta iyo qiiqa wasakhaysan.

 

Haddii aad rabto inaad si dheeraad ah u fahamto sababta idaacadaha ugu baahan yihiin filtarrada RF ee xirfadleyda ah, waxaa laga yaabaa inaad u baahato waxyaabaha soo socda

 

Sidee loo abuuraa Harmonics?

 

Soo noqnoqoshada ku dhaca tiro sax ah oo soo noqnoqoshada ah waxa loo yaqaan harmonics. Si kale haddii loo dhigo, harmonics waa gudbin aan la rabin, taas oo ah tiro badan oo ah inta jeer ee la filayo. Gudbintan aan la rabin waxay ku dhacdaa heer awood ka hooseeya gudbinta la rabo.

 

Sida aan wada ognahay, waxaa jira qalab aan laga maarmi karin oo ka jira idaacadaha, taas oo ah, gudbiyaasha raadiyaha. Haddii 1kW ama 10kW gudbiyaha si gaar ah loo nakhshadeeyo, iyo qaybta aasaasiga ah ee RF ee gudbiyaha waxaa lagu qalabeeyaa shaandheynta band-pass, laakiin ku dhawaad ​​gudbiyaha RF kasta ayaa soo saari doona qaar ka mid ah is-waafajinta sii daynta

 

Harmonics sidoo kale waxaa loo arkaa inay tahay sabab suurtagal ah faragelinta RF. Qaababka mowjadaha qaarkood, sida mowjadaha labajibbaaran, mowjadaha sawtooth-ka, iyo hirarka saddex-geesoodka ah, waxay ka kooban yihiin tamar badan inta jeer ee is-waafaqsan.

 

Sidee loo abuuraa qiiqa wasakhaysan?

 

Si ka duwan sida harmonics, qiiqa xunxun ma dhaco marka inta jeer ee wax gelinta la labanlaabo; Uma ay faafin ula kac. Sii daynta wasakhaysan waa qiiq shil ah, oo loo yaqaan splash. Waxay yihiin natiijada isdhexgalka, faragelinta korantada, beddelka soo noqnoqda, ama iswaafajinta.

Fadlan sii wad akhrinta haddii aad rabto inaad wax badan ka ogaato filtarrada RF. 

 

Q1: Sidee bay filtarrada RF u shaqeeyaan siyaabaha kale marka laga reebo FM/TV station?

 

Filters-ka RF waa qaybo muhiim ah oo ka mid ah tignoolajiyada wireless-ka, filtarrada RF waxaa loo adeegsadaa qaataha raadiyaha si nooca saxda ah oo kaliya loogu madadalo karo iyadoo la shaandheynayo xadhkaha kale ee aan la rabin ee soo noqnoqda. Shaandhooyinka RF waxaa loo qaabeeyey qaab ay si fudud ugu shaqayn karaan soo noqnoqoshada inta u dhaxaysa dhexdhexaad ilaa xad aad u sarreeya, tusaale ahaan megahertz iyo gigahertz. Sababtoo ah sifada ay ku shaqeyso, waxaa inta badan loo isticmaalaa qalabka sida raadiyaha baahinta, isgaarsiinta wireless, iyo telefishinka, iwm.

 

Shaandhooyinka RF waxay shaandheyn karaan qaylada ama waxay yareynayaan faragelinta calaamadaha dibadda ee saameyn kara tayada ama waxqabadka nidaamka isgaarsiinta. Maqnaanshaha filtarrada saxda ah ee RF ee meesha ku jira waxay dhibaato ku keeni kartaa isu-gudbinta calaamadaha calaamadaha taasoo ku dambayn karta inay dhaawacdo habka isgaarsiinta.

 

Iyadoo filtarrada RF ee saxda ah ay ku jiraan, faragelinta dibadda oo ay weheliso khalkhalka calaamadda ee ay soo saarto nidaamka isgaarsiinta deriska ayaa si fudud loo xannibi karaa. Tani waxay ilaalinaysaa tayada is-dhaafsiga calaamadaha la rabo iyadoo si fudud u sifaynaysa dhammaan soo noqnoqda calaamadaha aan la rabin.

 

Sidaa darteed, filtarrada RF waxay door muhiim ah ka ciyaaraan nidaamka isgaarsiinta wireless-ka, tusaale ahaan satellite-ka, radar, nidaamka wireless-ka mobaylada, iyo in ka badan. 

 

Guud ahaan, filtarrada ayaa ah kuwa fudud waxayna kaa caawin karaan kor u qaadida waxqabadka soo noqnoqda calaamadaha. Xaaladda halka filtarrada RF ay ku guuldareystaan ​​inay bixiyaan waxqabadka la filayo, markaa waxaad sahamin kartaa doorashooyin kale oo kala duwan, mid ka mid ah waa ku darida cod-weyneeye naqshadeyntaada. Laga soo bilaabo cod-weyneeye Trellisware ilaa mid kasta oo kale oo awood RF ah, waxaad u bedeli kartaa soo noqnoqda calaamadaha hoose kuwa sare; sidaas darteed kor loogu qaado waxqabadka guud ee naqshadaha RF.

 

Intaa waxaa dheer, filtarrada RF waxay sidoo kale door muhiim ah ka ciyaaraan deegaanka taleefanka gacanta. Marka ay timaado mobilada, waxay u baahan yihiin qadar go'an oo band ah si ay si sax ah u qabtaan. Maqnaanshaha shaandhada saxda ah ee RF, kooxaha kala duwan looma oggolaan doono inay isla mar wada noolaadaan taasoo ka dhigan in kooxaha qaarkood la diidi doono, tusaale ahaan Nidaamka Satellite Navigation (GNSS), badbaadada dadweynaha, Wi-Fi, iyo in ka badan. Halkan, filtarrada RF waxay ciyaaraan door muhiim ah iyagoo u oggolaanaya dhammaan guutooyinka inay wada noolaadaan isku mar.

 

Waad ku mahadsan tahay horumarka R&D ee qaan-gaadhka ah ee FMUSER, waxaanu kuu daboolnaa daraasiin filtarrada kala duwan adiga, fadlan hubi inaad la xidhiidho kooxdayada iibka Haddii aadan hubin kuwa ugu fiican xaruntaada baahinta, kooxdayada iibka iyo farsamada ayaa sugi doona DHAGAHA OO DHAN.

 

Q2: Sidee u Sameeyaa Shaandhaynta RF?

 

Guud ahaan, filtarrada RF waxay ka kooban yihiin resonators oo isku xidhan waxaana loo qaabeeyey qaybo falcelin aan toos ahayn sida capacitors, inductors, iyo (in ka yar inta badan) transformers RF, kuwaas oo isku xidhan inductors. Shaandheeyayaashu inta badan waa toosan, oo marka loo baahdo nooc ka mid ah kordhinta waxa lagu dari karaa cod-weyneyaal RF ah oo lagu hirgeliyay transistor-ka RF (ha ahaato laba-cirifoodka ama saameeynta goobta). Shaandheeyayaashu waa lagama maarmaan marka ay timaaddo shaandhaynta calaamadaha aan loo baahnayn ee gelaya spectrum raadiyaha. Waxaa loo isticmaalaa marka lagu daro qalabka elektarooniga ah ee kala duwan. Si kastaba ha ahaatee, isticmaalkeeda ugu muhiimsan wuxuu ku yimaadaa qaybta soo noqnoqda raadiyaha.

 

Filterka hooseeya ee baaska, wareeggiisa kaas oo u oggolaanaya kaliya qaybaha soo noqnoqda ee hooseeya oo xannibaya dhammaan qaybaha kale ee soo noqnoqda waxaa loo yaqaan shaandheynta hoose. Magaca LPF laftiisu wuxuu muujinayaa inta jeer ee tirada yar.

 

Iyada oo ku saleysan codsiga iyo cabbirka qalabka wireless-ka, waxaa jira noocyo badan oo filtarrada, ie filtarrada godka, filtarrada qorshaynta, filtarrada korantada, filtarrada dielectric, filtarrada coaxial (aan la xiriirin fiilada coaxial), iyo in ka badan.

 

FMUSER waa soo-saare xirfad leh filtarrada RF harmonics. Waxaan haysanaa kaydka aqoonta qalabka baahinta ugu xirfadaysan iyo kooxda farsamada. Haddii aad wax su'aalo ah ka qabto filtarrada RF inta aad akhrinayso wadaagan, soo dhawoow si aad u weydiiso kooxdayada farsamada taageero.

 

Q3: Immisa Nooc oo Filterka RF ah ayaa jira iyo maxay yihiin sida saxda ah?

 

Shaandhooyinka Soo noqnoqda Raadiyaha waa nooc gaar ah oo wareeg ah oo u oggolaanaya calaamadaha saxda ah inay gudbaan inta ay baabi'inayaan calaamadaha aan loo baahnayn. Marka ay timaado dhinaca shaandhada shaandhada, waxaa jira afar nooc oo shaandhada RF aasaasiga ah, ie; heer sare; band-baas; iyo band-diidi (ama filtarrada darajada). Shaandhooyinka RF ee ugu caansan waxay leeyihiin qaab-dhismeedka jaranjarada, iyo "booska" qaybaha (inductors iyo capacitors) waa waxa qeexaya nooca; qiyamka qaybaha ayaa qeexaya inta jeer ee calaamadaha ay xannibaan ama aysan xannibin.

 

  • Shaandheynta Gudub Hoose - Shaandheeyaha Lowpass - LPF

 

Shaandheeyaha baaska hooseeya waa midka kaliya ee u oggolaanaya soo noqnoqoshada hooseeya inay dhex maraan isla mar ahaantaana, yareynaya soo noqnoqoshada calaamadaha kale. Qadarka hoos u dhaca inta jeer ee calaamaduhu marka ay dhex maraan bandpass waxaa go'aamiya arrimo badan sida shaandhada shaandhada, qaabka, iyo tayada qaybaha, iwm. baasaboorka si uu u gaaro diidmadiisa kama dambaysta ah.

 

 

LPF 

filtarrada kaadhka hooseeya waxay ku yimaadaan qaabab kala duwan. Codsiga ugu weyn ee shaandhadan ayaa ah xakamaynta harmonics-ka cod-weyneeye RF. Dabeecaddani waa muhiim tan iyo markii ay ka caawiso ka hortagga faragelinta aan loo baahnayn marka ay timaado xadhkaha gudbinta ee kala duwan. Inta badan, filtarrada kaarka hooseeya waxaa loo adeegsadaa codsiyada maqalka ah waxayna shaandheeyaan dhawaaqyada wareeg kasta oo dibadda ah. Ka dib marka la sifeeyo calaamadaha soo noqnoqda sare, soo noqnoqda calaamaduhu waxay helayaan tayo cad oo qallafsan.

 

  • Shaandheynta Sare ee Sare - Filterka Sare ee Sare - HPF

 

Si ka duwan shaandhada baaska hoose, filter-ka sare ee baska (HPF) wuxuu u ogolaanayaa oo kaliya calaamada soo noqnoqda sare inay dhex maraan. Run ahaantii, filtarrada baaska sare aad bay u dhammaystiran yihiin filtarrada kaadhka hoose maadaama labadoodaba loo isticmaali karo si wadajir ah si loo soo saaro shaandhada baasaska. Naqshadeynta shaandhada baaska sare waa mid toos ah oo hoos u dhigaysa soo noqnoqoshada ka hooseeya barta bilowga.

 

 

HPF 

Caadi ahaan, filtarrada baaska sare waxaa lagu isticmaalaa hababka maqalka kuwaas oo dhammaan soo noqnoqda hoose lagu sifeeyo. Intaa waxaa dheer, waxaa loo isticmaalaa in laga saaro bass ee ku hadla yar yar, iyo xaalado badan; filtarradan ayaa si gaar ah loogu dhisay sameecadaha. Si kastaba ha noqotee, haddii ay timaado mashruuc kasta oo DIY ah, filtarrada baasaaska sare si fudud ayaa loogu xidhi karaa nidaamka.

 

  • Shaandheeyaha Gudubka Baaskiilka - Filterka Baadhitaanka - BPF

 

Filter-ka bandpass (BPF) waa wareeg u oggolaanaya calaamadaha laba jeer oo kala duwan inay dhex maraan oo ay yareeyaan calaamadaha aan ku dhex jirin xadka aqbalaadda. Inta badan filtarrada bandpass waxay ku xiran yihiin il kasta oo koronto oo dibadda ah waxayna isticmaalaan qaybo firfircoon, sida wareegyada isku dhafan iyo transistor-yada. Noocyada noocaan ah waxaa loo yaqaan filtarrada bandpass firfircoon. Dhanka kale, filtarrada band-yada qaarkood ma adeegsadaan ilo koronto oo dibadda ah waxayna si weyn ugu tiirsan yihiin qaybaha dadban, ie inductors iyo capacitors. filtarradan waxaa loo yaqaan filtarrada bandpass dadban.

 

 

Shaandheeyayaasha kaarka Band waxaa inta badan lagu isticmaalaa qaataha iyo gudbiyaasha wireless-ka. Shaqadeeda ugu weyn ee gudbiyaha waa in la xaddido xawliga xawliga ee signalka wax soo saarka ilaa ugu yaraan si xogta lagama maarmaanka ah loogu gudbiyo xawaaraha iyo qaabka la rabo. Marka ay timaado soo-dhowrka, shaandheynta baasaska guutadu waxa ay ogolaataa in tiro la doonayo oo taxanayaal ah oo keliya in la dejiyo ama la maqlo, iyada oo la jarayo calaamadaha kale ee ka imanaya mawjadaha aan loo baahnayn.

 

BPF

 

Isku soo wada duuboo, marka shaandhada bandpass si fiican loo naqshadeeyay, waxay si fudud u kordhin kartaa tayada calaamadaha, isla markaana, waxay yarayn kartaa tartanka ama faragelinta calaamadaha.

 

  • Band Diidey Filter - Band Jooji Filter - Diid Filter - BSF

 

Mararka qaarkood waxaa loo yaqaannaa filter joojinta band (BSF), diidmada band waa shaandheyn u oggolaanaysa inta badan inta jeer ee soo noqnoqda inay dhex maraan iyada oo aan isbeddelin. Si kastaba ha ahaatee, waxay hoos u dhigtaa soo noqnoqoshada noocaan oo kale ah oo ka hooseeya heer aad u gaar ah. Waxay u shaqeysaa si ka soo horjeeda kan shaandhada bandpass.

 

 

Asal ahaan, shaqadeedu waa inay ka gudubto soo noqnoqoshada eber ilaa meesha ugu horeysa ee la gooyey ee soo noqnoqda. Inta u dhaxaysa, waxay dhaaftaa dhammaan soo noqnoqoshada ka sarreeya barta labaad ee goynta ee inta jeer. Si kastaba ha ahaatee, waxay diiday ama xannibaysaa dhammaan soo noqnoqda kale ee u dhexeeya labadan qodob.

 

BSF 

Isku soo wada duuboo, filtarku waa shay u ogolaanaya calaamaduhu inay dhex maraan iyadoo la kaashanayo baaska. Taasi waxay tidhi, xadhiga joogsiga ee shaandhada ku jira waa meesha ay soo noqnoqoshada qaarkood diidaan shaandhayn kasta. Ha ahaato baas sare, baas hoose, ama baasbaas, shaandhada ugu habbooni waa ka aan wax khasaare ah ka soo bixin baasabka. Si kastaba ha ahaatee, dhab ahaantii, ma jiraan wax la yiraahdo shaandheyn ku habboon maadaama baska uu la kulmi doono khasaaro soo noqnoqda oo aan suurtagal ahayn in la gaaro diidmo aan dhammaad lahayn marka ay timaado xirmada joogsiga.

1. Hawlgalka Filterka RF

 

Shaandheyntan kaarka hooseeya waxaa loogu talagalay in lagu dhimo oo inta badan kiisaska la baabi'iyo faragelinta telefishinka ee ay keento tamarta is-waafajinta ee ka dhex abuurma gudbiyaasha FM.

 

Shaandheeyaha waa laba jiho taasoo la micno ah in lagu rakibi karo labada dhinac. Moodeelka shaandhada gudbiyaha ee 20kW FM A wuxuu muujinayaa hoos u dhac ku yimaadda soo noqnoqoshada ka sarreeya 140 MHz sida ku cad qalooca jawaabta hoose.

 

 

OGEYSIIS: Digniinta gelinta ee shaandhada 20kW waa in aanay ka badan 20000 watts. Isticmaalka awooda sare waxay si joogta ah u dhaawacaysaa shaandhada waxayna burinaysaa dammaanadda

 

2. Rakibaadda Filterka RF

 

  • Shaandheeyaha waa in lagu rakibaa meel u dhow wax soo saarka gudbiyaha sida la taaban karo 
  • Isticmaalka 3 1/8" Xidhiidhiyayaasha EIA oo leh xidhiyaal lab ah oo ku yaal labada daraf.

 

TAXADIR: Filter-ku waxa laga yaabaa in uu kululaado inta lagu jiro hawsha, tani waa calaamad muujinaysa in ay shaqadeeda qabsanayso iyada oo la baabi'inayo tamarta harmonic qaabka kulaylka.

 

3. Cabashada ka timid TV-ga Cable ee Xaafadaada

 

Haddii gudbiyahaagu uu farageliyo nidaamka TV-ga fiilo, dhibka waxaa laga yaabaa in aan lagu xalin isticmaalka shaandhada hoose ee baaska. Qaar ka mid ah shirkadaha fiilada ee aan ku qaadin kanaalada FM-ka nidaamkooda ayaa laga yaabaa inay kanaalada TV-ga dhigaan kooxda baahinta FM-ta. Haddi ay arintu sidaas tahay, inta jeer ee aasaasiga ah (sidade) ayaa laga yaabaa inay keento faragelinta oo shaandhada waxay noqon doontaa mid aan waxtar lahayn. Macluumaad dheeraad ah kala xidhiidh shirkadda xadhkaha ee xaafaddaada. Xaaladaha qaarkood, shirkadda fiilada waxay xallin kartaa dhibaatada iyada oo beddeleysa fiilkii hore ama duugoobay.

1. Sababaha ka dambeeya qiiqa iswaafajinta iyo qiiqa

 

  • Gudbiyaha raadiyaha hiwaayadda ee si liidata u shaqeeya ayaa laga yaabaa inuu sabab u noqdo iswaafajinta awoodda sare leh. Waxay sidoo kale saameyn doontaa gudbinta raadiyaha ee qalabka kale ee u dhow.
  • Amplifiers sidoo kale waxay soo saaraan harmonics. Sida aynu wada ognahay, waxay qalloocin doonaan mawjadaha signalada, ama ilaa xad ma aha kuwo aan toos ahayn. Naqshadaynta idaacadaha liidata waxay kordhin doontaa heerarka iswaafajinta. Sidaa darteed, waxaad yareyn kartaa faragelinta adigoo si fudud u qaadanaya naqshad wanaagsan oo madal ah.
  • Xitaa haddii uusan qalabku si firfircoon u gudbin, waxay soo saari doontaa qiiqa xunxun. Tan waxa laga yaabaa inay sabab u tahay calaamadaha xawaaraha sare leh, sahay koronto oo buuq badan, ama dhibaatooyin kale oo calaamad ah. Haddii qalabku si firfircoon u gudbiyo, qiiqa xunxun wuxuu u dhici karaa laba sababood:
  • Xadhkaha korantada ee ku xidhan raadiyaha waxa uu ka kooban yahay buuq badan oo soo noqnoqda. Waxay keentaa in cod-weyneeye raadiyaha uu soo saaro wareegyo gaar ah.
  • Qaybaha qaar ee PCB-ga ayaa soo qaada inta jeer ee aasaasiga ah.

 

OGEYSIIS: Gudbinta xunxun ayaa laga yaabaa inay dhacdo haddii gudbiyaha u gudbiyo si khaldan meel ka baxsan xajmiyeedka saxda ah ama qaabka la isticmaalay. Xaaladdan oo kale, gudbiyaha ayaa soo saara firiiric, kaas oo faragelin kara saldhigyada kale ee loo habeeyay wareegyada u dhow xargaha soo noqnoqda.

 

2. Sidee loo yareeyaa Saamaynta Harmonics iyo Emission-ka Wasagsan?

 

Tallaabooyinka soo socda ayaa la qaadi karaa si loo xakameeyo heerka faragelinta:

 

  • Hubi gudbiyaha si aad u yarayso qiiqa wasakhaysan ee joogtada ah.
  • Hubi in qalabka qeylada badan iyo shirarka ay ka fog yihiin anteenada.
  • Ka fogow isticmaalka gudbiyaasha raadiyaha hiwaayadda leh ee hawlahooda liita.

 

OGAYSIIS: qiiqa isku-dhafan iyo kuwa beenta ah lama iska ilaalin karo laakiin waa la yarayn karaa ilaa xad. Calaamad kasta oo is-waafajisa oo ka baxsan kanaalka loo qoondeeyay ee gudbiyaha waxaa loo arkaa gudbinta been abuur ah. Badanaa waa natiijada qalabka si liidata u shaqeeya ama faragelinta deegaanka.

 

La wadaag dheeraad ah oo ku saabsan Faragelinta Raadiyaha

 

Kuwa soo socdaa waa aqoonta raadiyaha oo dheeri ah oo la wadaagayo waxa faragelinta raadiyaha ay tahay iyo sida loo yareeyo saameynta faragelinta raadiyaha. Waxaan rumaysanahay in hore loo helay macluumaad ku filan filtarrada RF, laakiin qaar ka mid ah gudbinta calaamadaha raadiyaha iyo dhibaatooyinka soo dhaweynta ayaa weli ka jira nolosha dhabta ah. Macaamiil badan oo ku sugan goobta raadiyaha ayaa si xun ugu tufay faragelinta raadiyaha waxayna naga codsadeen inaan u samayno xalal gaar ah iyaga. Haddaba, waxaanu si kooban u qeexi doonaa aqoonta dhabta ah ee ku saabsan faragelinta raadiyaha ee boqollaal eray oo hadhay

 

1. Qalab noocee ah ayay saameyn kartaa Faragelinta Raadiyaha?

 

Qalabka raadiyaha iyo kuwa aan raadiyaha ahaynba waxaa si xun u saameyn kara calaamadaha raadiyaha. Aaladaha raadiyaha waxaa ka mid ah idaacadaha AM iyo FM, telefishinada, telefoonada aan xadhkaha lahayn, iyo is dhex galka wireless-ka. Qalabka elektaroonigga ah ee aan raadiyaha ahayn waxaa ka mid ah hababka maqalka ee stereo, telefoonnada fiilsan, iyo is-dhexgalka fiilooyinka caadiga ah. Dhammaan qalabkan waxaa carqaladayn kara calaamadaha raadiyaha.

 

2. Maxaa Sababi Kara Faragelinta Raadiyaha?

 

Faragelintu waxay badanaa dhacdaa marka war-fidiyeyaasha raadiyaha iyo qalabka elektaroonigga ah lagu shaqeeyo meel u dhow midba midka kale. Faragelinta waxaa keenay:

  • Qalabka gudbinta raadiyaha oo si khaldan loo rakibay;
  • Digniinta raadiyaha oo aad u daran oo ka timid gudbiye dhow;
  • Calaamadaha aan la rabin (oo loo yaqaan shucaaca xun) ee uu dhaliyo qalabka gudbinta; iyo
  • Aan ku filnayn gaashaanka ama shaandhaynta qalabka elektaroonigga ah si looga hortago inay soo qaadaan calaamadaha aan loo baahnayn.

 

3. Maxaad Qaban Kartaa?

 

  1. Isku day inaad ka hortagto dhibaatooyinka faragelinta ka hor intaanay dhicin. La tasho maamulka degmada si aad u ogaato xeerarka khuseeya anteenooyinka iyo dhismayaasha taawarada. Markaad haysato qorshe rakibaad oo buuxinaya shuruudaha degmada, la hadal deriskaaga. Sharax waxaad rabto inaad sameyso iyo sababta. U hubso inaad ku dadaali doonto inaad ka hortagto dhibaato kasta. Xusuusi iyaga in GRS iyo hawl-wadeennada raadiyaha hiwaayadda ahi ay inta badan qabtaan adeeg dadweyne oo muhiim ah iyaga oo caawinaya maamullada maxalliga ah marka ay jiraan xaalado degdeg ah iyo munaasabado dadweyne oo waaweyn.
  2. Hubi in qalabkaaga si sax ah loogu rakibay. Anteenada idaacaddu waa in ay ka fogaato guryaha deriska la ah inta ugu macquulsan kana fogaato xadhkaha korontada taasoo saameyn ku yeelan karta shaqadeeda. Si taxadar leh u akhri qaybta, Rakibaadda Idaacaddaada.
  3. Ka shaqee saldhiggaaga adigoo maskaxda ku haya deriskaaga. Xaddid awoodda gudbiyaha, halka ay suurtagal tahay, ilaa heerka ugu hooseeya ee looga baahan yahay isgaarsiin ku filan. Saldhigyada GRS ee gudbinta, cod-weyneyaasha korontada lama oggola, wax soo saarka ugu badan ee anteenada waa inuusan ka badnaan 4 watts (hal dhinac ah; 12watts peak).
  4. Hubi in qalabkaaga lagu hayo xaalad wanaagsan sida waafaqsan shuruudaha farsamo. Waqti ka waqti, waa in aad xaqiijisaa in inta jeer ee gudbinta ay sax tahay, xadhkaha xadhkaha goostay uu ku jiro xadka shaqada, fiilooyinka saldhiga, anteenada, iyo nidaamka dhulka ay xaalad fiican ku sugan yihiin.

 

4. Sidoo kale waa inaad:

 

  • U nugul dhibaatooyinka faragelinta iskuna day inaad sida ugu dhakhsaha badan u xalliso.
  • La shaqee deriskaaga si aad u ogaato waxa dhibaatada keenaya iyo waxa ka dhigaya mid ka sii wanaagsan.
  • Markaad isku dayayso inaad xal farsamo u hesho faragelinta, xaddid awoodaada gudbiyaha iyo wakhtiyada shaqada. Tixgeli in aad gabi ahaanba xidhid saldhigaada ilaa inta dhibaatada la saxayo.
  • Dareen Xoriyad inaad na waydiiso haddii aad la kulanto dhibaatooyin badan
