PTB 20220
15 Watts, 915–960 MHz
Cellular Radio RF Power Transistor
Description
The 20220 is a class AB, NPN, common emitter RF power transistor
intended for 25 Vdc operation across the 915 to 960 MHz frequency
band. Rated at 15 watts minimum output power for PEP applications,
it may be used for both CW and PEP applications. Ion implantation,
nitride surface passivation and gold metallization ensure excellent
device reliability. 100% lot traceability is standard.
