WITH 6.2 dB GAIN .400 x .400 2LFL (S036) hermetically sealed ORDER CODE AM82731-025 BRANDING 82731-25 DESCRIPTION The AM82731-025 device is a high power silicon bipolar NPN transistor specifically designed for S-Band radar pulsed output and driver applications. This device is capable of operation over a wide range of pulse widths, duty cycles, and temperatures and can withstand a 3:1 output VSWR with a +1dB input over drive. Low RF thermal resistance, refractory/gold metallization, and automatic wire bonding techniques ensure high reliability and product consistency (including phase characteristics). The AM82731-025 is supplied in the Hermetic Metal/Ceramic package with internal Input/Output impedance matching circuitry, and is intended for military and other high reliability applications.
