PTB 20188
4 Watts P-Sync, 470鈥?60 MHz
UHF TV Linear Power Transistor
Description
The 20188 is an NPN common emitter UHF power transistor intended
for 25 Vdc class A operation from 470 to 860 MHz. It is rated at 4
watts output power, and 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.
