Description
PTB 20167
60 Watts, 850–960 MHz
RF Power Transistor
The 20167 is an NPN, common base RF power transistor intended
for 24 Vdc operation from 850 to 960 MHz. Rated at 60 watts minimum
output power, it is specifically designed for class C power amplifier
applications. Ion implantation, nitride surface passivation and gold
metallization are used to ensure excellent device reliability . 100% lot
traceability is standard.
