Cellular Radio RF Power Transistor
Description
The 20179 is an NPN, common emitter RF power transistor intended
for class A, 26 Vdc operation from 1.8 to 2.0 GHz. Rated at 0.4 watt
minimum output power, it 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.
