Malangizo Othandizira Kupanga

Zosintha Zokondera

Kusintha	Ubwino wake	Ntchito Wamba
Common Emitter	Kuwonjezeka kwakukulu kwamagetsi	Magawo okulitsa
Common Collector	Kupeza bwino kwakanthawi	Magawo a buffer
Common Base	Kuyankha pafupipafupi kwambiri	RF ntchito

Ma Parameters Ofunika Kwambiri

Zolinga za kutentha
- Malire a kutentha kwapakati
- Kukana kutentha
- Zofunikira pakuyatsa kutentha
Malo Ogwirira Ntchito Otetezeka (SOA)
- Ma voteji apamwamba kwambiri
- Zolepheretsa panopa
- Malire otaya mphamvu

Pezani Thandizo Laukadaulo

Kudalirika ndi Kukhathamiritsa Kwantchito

Njira Zabwino Kwambiri Zogwiritsira Ntchito

Chitetezo Chozungulira
- Base resistor kukula
- Voltage clamping
- Kuchepetsa kwapano
Thermal Management
- Kusankha kwa sink ya kutentha
- Kugwiritsa ntchito matenthedwe amafuta
- Malingaliro a Airflow

Maupangiri Owonjezera Kuchita

Konzani masanjidwe a PCB kuti agwire bwino ntchito
Gwiritsani ntchito ma bypass capacitor oyenera
Ganizirani zotsatira za parasitic muzogwiritsa ntchito pafupipafupi
Gwiritsani ntchito njira zoyenera zoyambira pansi

Mavuto Wamba ndi Mayankho

Chizindikiro	Chifukwa Chotheka	Yankho
Kutentha kwambiri	Kujambula kochulukira	Chotsani kutentha, onjezerani kutentha
Kupindula kosauka	Kukondera kolakwika	Sinthani zotsutsa zokondera
Kugwedezeka	Nkhani zamapangidwe	Limbikitsani maziko, onjezerani modutsa
