| AM82731-012 RF & MICROWAVE TRANSISTORS S-BAND RADAR APPLICATIONS .REFRACTORY/ .EMI .LOW .I .OVERLAY .METAL/ .P DESCRIPTION PRELIMINARY DATA G OLD METALLIZATION T TER SITE BALLASTED THERMAL RESISTANCE NPUT/OUTPUT MATCHING GEOMETRY CERAMIC HERMETIC PACKAGE OUT = 12 W MIN. WITH 6.0 dB GAIN .400 x .400 2LFL (S036) hermetically sealed ORDER CODE BRANDING AM82731-012 82731-12 The AM82731-012 device is a high power silicon bipolar NPN transistor specifically designed for SBand radar pulsed output and driver applications. This device is capable of operaion over a wide range of pulse widths, duty cycles, and temperatures and can withstand a 3:1 output VSWR with a + 1 dB input overdrive. Low RF thermal resistance, refractory/gold metallization, and automatic wire bonding techniques ensure high reliability and product consistency (including phase characteristics). The AM82731-012 is supplied in the Hermetic Metal/Ceramic package with internal Input/Output impedance matching sircuitry, and is intended for military and other high reliability applications.
