0.7 Watts, 1525–1660 MHz
INMARSAT RF Power Transistor
Description
The 20077 is a class A, NPN, common emitter RF power transistor
intended for 26 Vdc operation from 1525 to 1660 MHz. Rated at 0.7
watt minimum output power, it may be used for both CW and PEP
applications. Ion implantation, nitride surface passivation and gold
metallization ensure excellent device reliability. 100% lot traceability
is standard.
