Shaandhaynta godka UHF

A UHF godadka filter is a nooca of radio inta jeer (RF) filter used ilaa kala gooni ah baxay aan loo baahnayn calaamadaha at UHF Joogtaynta. It is inta badan used in UHF warbaahin saldhigyada ilaa filter baxay faragelinta calaamadaha, sida as ku xiga channel calaamadaha, HarmoonICS, iyo Nacasnimo calaamadaha, in si ilaa loo hagaajiyo ka oo tayo leh of ka helay signalka. UHF godadka filtarrada waa muhiim ah ilaa UHF radio baahinta maxaa yeelay, waxay awooddo I caawi yareeyo faragelinta iyo loo hubiyo in oo keliya ka la doonayo signalka is helay. The isticmaalka of a UHF godadka filter in a UHF warbaahin Idaacadda waxay u baahan tahay an injineer or farsamo yaqaan ilaa rakibi ka filter, laxan it ilaa ka la doonayo inta jeer, iyo la qabsado it as loo baahan yahay ilaa loo hubiyo ugu fiican waxqabadka.

Waa maxay shaandhada godka UHF?
Shaandheeyaha daloolka UHF waa nooc shaandhada soo noqnoqda raadiyaha loo isticmaalo in lagu go'doomiyo, dhaafo, ama lagu diido soo noqnoqoshada raadiyaha ee xadka ultra-high-frequency (UHF). Waxay ka kooban tahay isku-dar ah wareegyo toosan iyo godadka, kuwaas oo u shaqeeya sidii resonators. La mid ah shaandhada godka UHF waa shaandheynta bandpass UHF.
Waa maxay codsiyada ugu badan ee filtarrada godka UHF?
Codsiyada ugu badan ee filtarrada godka UHF waa baahinta raadiyaha iyo talefishinka, isgaarsiinta satalaytka, navigation raadiyaha, iyo nidaamyada telemetry. Waxaa loo isticmaalaa si loo yareeyo faragelinta iyo hagaajinta saamiga signal-ilaa-sanqa ee nidaamka. Shaandhooyinka daloolka UHF ayaa si gaar ah waxtar u leh codsiyada halka loo baahan yahay in la go'doomiyo xargaha soo noqnoqda ee cidhiidhiga ah, sida nidaamyada isgaarsiinta wirelesska. Waxaa sidoo kale loo adeegsadaa WiFi iyo shabakadaha gacanta, raadiyaha iyo telefishinada ku celiska ah, nidaamyada radar, iyo nidaamyada isgaarsiinta militariga, iyo codsiyada kale.
Sida loo isticmaalo shaandhada godka UHF baahinta TV-ga?
1. Ku rakib filtarka nidaamka anteenada adigoo raacaya tilmaamaha soo saaraha.

2. Hubi in shaandhada si fiican loo sugay iyo in nidaamka anteenadu si ku filan u qotonto.

3. Deji tirada inta jeer ee shaandhada baasaska si ay u daboosho tirada inta jeer ee la rabo.

4. Hubi in filtarku leeyahay khasaare gelin ku filan si loo hubiyo in tamarta la sii daayo ay ku sii jirto xadka.

5. Si joogto ah ula soco waxqabadka shaandhada si aad u hubiso inay u shaqaynayso sidii la filayey.

6. Ka digtoonow dhibaatooyinka shaandhada caadiga ah sida calaamadaha band ka baxsan iyo qalloocinta iswaafajinta.

7. Si wakhti ah u hubi xidhiidhada filtarka si aad u hubiso inay ammaan yihiin.

8. Iska hubi inaad isticmaashid filtar ku haboon arjiga, maadaama dhamaan filtarrada aysan ku haboonayn codsiyada oo dhan.
Sidee filtarka godka UHF uga shaqeeyaa baahinta UHF?
Shaandheeyaha daloolka UHF ayaa loo adeegsadaa xarunta baahinta UHF si loo yareeyo faragelinta calaamadaha kale ee baahinta iyo si loogu oggolaado calaamadda la rabo inuu dhex maro. Shaandheeyaha wuxuu ka kooban yahay dhowr tuubbo oo bir ah oo loo habeeyey qaab gaar ah, tuubo kastana waxaa lagu hagaajiyay inta jeer ee kala duwan. Tuubooyinka waxa ay isku xidhan yihiin gudaha meel xidhan oo marka calaamada la rabo loo diro shaandhada, waxa ay maraan tuubooyinka u dhigma inta jeer ee ay xidhaan tuubooyinka kale. Tani waxay hubinaysaa in kaliya calaamadda la rabo loo oggol yahay inuu dhex maro shaandhada.
Waa maxay sababta filtarrada godka UHF loogu baahan yahay xarunta baahinta UHF?
Shaandheeyaha daloolka UHF waa qayb muhiim ah oo ka mid ah idaacada UHF sababtoo ah waxay ka ilaalisaa calaamada gudbiyaha idaacada inay farageliso calaamadaha kale ee isku midka ah. Waxa kale oo ay ka hortagtaa calaamadaha gudbiyaasha kale ee soo noqnoqonaya kala duwan si ay u farageliyaan calaamada gudbiyaha saldhigga. Shaandheeyaha daloolka UHF ayaa lagama maarmaan u ah xarunta baahinta UHF sababtoo ah waxay gacan ka geysataa hubinta in calaamada xaruntu tahay mid xooggan oo cad, iyada oo aan la faragelin calaamadaha kale.
Waa maxay noocyada filtarrada godka UHF iyo faraqa u dhexeeya?
Waxaa jira saddex nooc oo waaweyn oo miirayaasha daloolka UHF: Bandpass, Notch (Bandstop), iyo Highpass.

Shaandheeyayaasha Bandpass waxaa loogu talagalay inay dhaafaan kaliya kala duwanaansho soo noqnoqosho gaar ah, ama “band”, ee calaamadaha iyagoo xannibaya dhammaan soowoyinka kale.

Shaandhooyinka loo yaqaan 'Bandstop' waxaa loogu talagalay inay xannibaan soo noqnoqoshada soo noqnoqda ee gaarka ah, ama "band", calaamadaha marka ay gudbayaan dhammaan tamarta kale.

filtarrada Highpass waxaa loogu talagalay in ay dhaafaan soo noqnoqoshada sare iyada oo xannibaya soo noqnoqoshada hoose.

9. Ku tijaabi shaandhada leh koronto-dhaliye si aad u hubiso inuu si fiican u shaqeynayo.
10. Hubi in sawirka shaandhadu uu ku jiro heerar la aqbali karo.
Sida saxda ah ee loo dayactiro shaandhada godka UHF?
Dayactirka shaandhada godka UHF waxa lagu samayn karaa dhawr tillaabo. Marka hore, waa muhiim in la ogaado dhibaatada. Kormeer muuqaal ah shaandhada iyo qaybaha ka kooban yahay waa in la sameeyaa si loo hubiyo wixii go'ay, xidhiidhada dabacsan, ama calaamad kasta oo kale oo dhaawac ama cillad ah.

Haddii qaybo jaban la helo, waxaa muhiim ah in la go'aamiyo sababta fashilka ka hor inta aan la bedelin qaybaha dhaawacan. Haddii la go'aamiyo in dhibaatadu ay sabab u tahay cillad wax soo saarka ama cillad farsamo, markaa qaybaha waa in lagu beddelaa kuwo cusub.

Marka qaybaha cilladaysan la beddelo, shaandhada waa in dib la isugu keenaa iyadoo la raacayo tilmaamaha soo saaraha. Tan waxa ka mid noqon kara dib-u-xidhida qaybaha kala duwan iyo hagaajinta goob kasta oo shaandhada.

Ugu dambeyntii, filtarka waa in la tijaabiyaa si loo hubiyo in uu si sax ah u shaqeynayo. Haddii wax arrimo ah la helo, habka waa in lagu celiyaa ilaa filtarku si sax ah u shaqeynayo.
Sidee si sax ah loogu xirxiraa shaandhada godka UHF ka hor iyo ka dib dhalmada?
1. Dooro shay baakad ah oo liddi ku ah joogsiga, biyuhu, iyo kuwa aan shoogga lahayn.
2. Dooro xirmo si fiican loo daboolay oo bixin doona ilaalin ku filan inta lagu jiro gaadiidka.
3. Hubi in baakadu ay si fiican u xidhan tahay si aanay u soo gelin wax qoyaan ah ama wasakhaysan.
4. Hubi in xirmada si sax ah loo calaamadeeyay oo si cad u tilmaamayso waxa ku jira.
5. Hubi in baakadu ay si fiican u cabiran tahay shayga la raray.
6. Hubi in baakidhku si adag ugu xidhan yahay ama u xidhan yahay si looga hortago wax isbedel ah inta lagu jiro safarka.
7. Hubi inaad ku darto dukumeenti kasta oo lagama maarmaan ah ama shahaadooyinka looga baahan yahay shayga la raray.
8. Hubi inaad tixgeliso shuruud kasta oo dheeraad ah oo ku saabsan rarida ama maaraynta shayga, sida xaddidaadaha heerkulka ama gariirka.
Muxuu ka samaysan yahay daaha shaandhada UHF?
Daabka shaandhada daloolka UHF ayaa sida caadiga ah ka samaysan walxo dielectric ah, sida dhoobada, galaaska, ama balaastigga. Maaddadan dielectric waxay muhiim u tahay waxqabadka filtarka, maadaama ay go'aaminayso cadadka tamarta ee dhexmarta shaandhada. Haddii walxaha khaldan la isticmaalo, filtarka ayaa laga yaabaa inuu awoodi waayo inuu sifeeyo inta jeer ee la rabo, taasoo keentay waxqabad xumo. Intaa waxaa dheer, nooca walxuhu wuxuu saameyn karaa luminta gelinta filtarka, luminta soo noqoshada, iyo cabbirrada waxqabadka kale.
Waa maxay qaabka aasaasiga ah ee shaandhada daloolka UHF?
Qaab dhismeedka aasaasiga ah ee shaandhada godka UHF wuxuu ka kooban yahay afar qaybood oo waaweyn: boostada isku xirka, resonators, iris, iyo wax soo saarka.

Boostada isku-xidhka ayaa bixisa isku xirka korantada ee ka dhexeeya gelinta iyo soo saarista shaandhada. Waxa kale oo loo istcimaalaa in lagu hagaajiyo xadiga awoodeed ee ku xidhan galinta iyo soo saarida shaandhada.

Resonators-yadu waa qaybaha ugu muhiimsan ee shaandhada. Waxaa loo isticmaalaa si loo gaaro sifooyinka jawaabta soo noqnoqda ee la rabo.

Irisku waa saxan bir ah oo la hagaajin karo oo loo isticmaalo in lagu hagaajiyo inta jeer ee shaandhada. Caadi ahaan waxa loo isticmaalaa in lagu gaadho jawaab cidhiidhi ah oo ka badan xadka soo noqnoqda ee gaarka ah.

Wax soo saarka waxaa loo isticmaalaa in lagu bixiyo isku xirka korantada soosaarka shaandhada.

Waxqabadka iyo sifooyinka shaandhada waxaa lagu go'aamiyaa isku-dhafka qaybaha, naqshadooda, iyo hagaajinta iris-ka. La'aanteed mid ka mid ah qaababkan, filtarku si caadi ah uma shaqayn karo.
Sidee si sax ah loogu shaqeeyaa shaandhada godka UHF?
Qofka loo xilsaaray inuu maareeyo shaandhada godka UHF waa inuu si fiican u fahamsan yahay elektiroonigga oo uu yaqaanaa cabbirada raadiyaha-soo noqnoqda (RF), gaar ahaan marka la eego shaqada shaandhada. Waa inay sidoo kale aqoon u leeyihiin isticmaalka qalabka tijaabada iyo cabbiraadda, iyo sidoo kale mabaadi'da naqshadeynta anteenada iyo hagaajinta shaandhada. Waa inay sidoo kale khibrad u leeyihiin nidaamyada baahinta UHF oo ay awoodaan inay ciladeeyaan wixii dhibaato ah ee soo kordha.
