9 Watts, 610–960 MHz
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.
