PTB 20258
6 Watts, 915–960 MHz
Cellular Radio RF Power Transistor
Description
The 20258 is a class AB, NPN, common emitter RF power transistor
intended for 25 Vdc operation from 915 to 960 MHz. Rated at 6 watts
minimum output power, it may be used for both CW and PEP
applications. Ion implantation, nitride surface passivation and gold
metallization are used to ensure excellent device reliability. 100% lot
traceability is standard.
