The SD8250 is a high power Class C transistor specifically designed for TACAN/DME pulsed output
and driver applications.
SD8250 is designed for operation under moderate pulse width and duty cycle pulse conditions and is capable of withstanding 5:1 output VSWR at rated RF overdrive.
Low RF thermal resistance and computerized automatic wire bonding techniques of SD8250 ensure high reliability and product consistency.
The SD8250 is supplied in the AMPAC] Hermetic Metal/Ceramic package with internal Input/Output matching structures.
