Description
PTB 20074
14 watts, 1.477–1.501 GHz
Cellular Radio RF Power Transistor
The 20074 is a class AB, NPN, common emitter RF power transistor
intended for 26 Vdc operation from 1.477 to 1.501 GHz. Rated at 14
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.
