2.Power amplifier: idan aka kwatanta da transistor ikon amplifier, ajiyar wutar da ake buƙata ya bambanta.Wannan saboda lanƙwan ƙwanƙwasa na ƙarar bututu yana da santsi.Don kololuwar siginar kiɗan da aka yi ɗorewa, ƙarar bututun ba lallai bane ya haifar da yanayin yanke igiyar ruwa, amma yana sa ƙarshen kololuwar ta zama zagaye.Wannan shi ne abin da muke kira sau da yawa kololuwar shearing.Bayan amplifier na wutar lantarki na transistor a wurin da ake yin nauyi, murdiya marar layi tana ƙaruwa da sauri, wanda ke haifar da yanke igiyar ruwa mai tsanani zuwa siginar.Ba ya yin kololuwar zagaye, amma yana tsaftace shi da kyau.Wasu mutane suna amfani da ma'auni na juriya, inductance da capacitance don siffanta lasifikar, da kuma gwada ainihin ƙarfin fitarwa na nau'ikan manyan na'urori masu ƙarfi na transistor masu inganci.Sakamakon ya nuna cewa lokacin da kaya yana da motsi na lokaci, akwai madaidaicin amplifier mai lamba 100W, kuma ainihin ƙarfin fitarwa shine kawai 5W lokacin da murdiya ta kasance 1%!Don haka, zaɓin adadin ajiyar wutar lantarki na transistor:
High aminci amplifier: 10 sau
Ƙarfin wutar lantarki mai girma na farar hula: sau 6
Matsakaicin wutar lantarki na farar hula: sau 3 sau 4
Ƙarfin wutar lantarki na bututu na iya zama ƙarami sosai fiye da rabon da ke sama.
