PTB 20245
35 Watts, 2.1–2.2 GHz
Wide-Band CDMA Power Transistor
Description
The 20245 is a class AB, NPN common emitter RF power transistor
intended for 26 Vdc operation from 2.1 to 2.2 GHz frequency band.
Rated at 35 watts minimum output power for PEP applications, it is
specifically intended for operation as a final or driver stage in Wide
CDMA or TDMA systems. Ion implantation, nitride surface passivation
and gold metallization ensure excellent device reliability. 100% lot
traceability is standard.
