20 Watts P-Sync, 470860 MHz
UHF TV Linear Power Transistor
Description
The 20011 is an NPN common emitter UHF power transistor intended
for 26.5 Vdc class A operation from 470 to 860 MHz. It is rated at 20
watts (p-sync) output power, and 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.
