Tijaabadu waxay caawisaa in la hubiyo in transistor-ku si sax ah u shaqeeyo oo uu buuxiyo tilmaamaha sida soo saarista tamarta iyo hufnaanta.

6. Dib-u-habaynta: Dib u habeyn inta ka hartay wareegtada gudbiyaha si aad u wanaajiso oo aad magdhow u siiso transistor-ka beddelka si aad u hubiso gudbiyaha waxqabadkiisa ugu wanagsan.

Waa muhiim in la hubiyo in beddelka tamarta sare ee RF transistor uu buuxiyo shuruudaha lagama maarmaanka ah iyo shuruudaha hawlgalka ka hor inta aan la rakibin. Sidoo kale, waxaa muhiim ah in la raaco hababka badbaadada ee lagu taliyay, oo ay ku jiraan ku-meelaynta korantada ee saxda ah iyo maaraynta qalabka, marka la isku dayayo in la dayactiro transistor RF awood sare leh. Haddii sababta fashilku aysan muuqan, waxaa habboon in lala tashado injineer ama farsamoyaqaan aqoon u leh si looga hortago cillado kale.
