PTB 20264
10 Watts, 1.8–1.9 GHz
Cellular Radio RF Power Transistor
Description
The 20264 is an NPN, common emitter RF power transistor intended
for 26 Vdc class AB operation from 1.8 to 1.9 GHz. Rated at 10 watts
minimum output power, 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.
