PTB 20235
70 Watts, 2.1鈥?.2 GHz
Wideband CDMA Power Transistor
Description
The 20235 is a class AB, NPN, push-pull RF power transistor intended
for 26 Vdc operation from 2.1 to 2.2 GHz. Rated at 70 watts PEP
minimum output power, it is specifically intended for operation as a
final stage in Wide CDMA systems. Ion implantation, nitride surface
passivation and gold metallization ensure excellent device reliability.
100% lot traceability is standard.
