UHF Power Transistor

Description

The 20155 is an NPN common base RF power transistor intended

for 28 Vdc class C operation from 610 to 960 MHz. Rated at 9 watts

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.
