20 Watts, 1.35–1.85 GHz
RF Power Transistor
Description
The 20157 is an NPN common base RF power transistor intended
for 22–26 Vdc class C operation from 1.35 to 1.85 GHz. Rated at 20
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.
