PTB 20091
30 Watts, 470–860 MHz
UHF TV Linear Power Transistor
Description
The 20091 is an NPN, common emitter RF power transistor intended
for 25 Vdc class A operation from 470 to 860 MHz. It is rated at 30
watts P-sync output power. Ion implantation, nitride surface passivation
and gold metallization are used to ensure excellent device reliability.
100% lot traceability is standard.
