Description
PTB 20166
23 Watts, 675–925 MHz
Common Base RF Power Transistor
The 20166 is an NPN, common base RF power transistor intended
for 24–30 Vdc class C operation from 675 to 925 MHz. Rated at 23
watts minimum output power, it may be used for both CW and pulsed
applications. Ion implantation, nitride surface passivation and gold
metallization are used to ensure excellent device reliability . 100% lot
traceability is standard.
