WITH 8.0 dB GAIN ORDER CODE SD8250 hermetically sealed BRANDING STAN250A DESCRIPTION PIN CONNECTION The SD8250 is a high power Class C transistor specifically designed for TACAN/DME pulsed out- put and driver applications. This device is designed for operation under mod- erate 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 au- tomatic wire bonding techniques ensure high re- liability and product consistency. The SD8250 is supplied in the AMPACTM Hermetic 1. Collector 3. Emitter Metal/Ceramic package with internal Input/Output 2. Base 4. Base matching structures. ABSOLUTE MAXIMUM RATINGS (T case = 25
