PTB 20171
25 Watts, 935–960 MHz
Cellular Radio RF Power Transistor
Description
The 20171 is a class AB, NPN, common emitter RF power transistor
intended for 24 Vdc operation from 935 to 960 MHz. Rated at 25
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.
