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.
