| AM81214-015 RF & MICROWAVE TRANSISTORS L-BAND RADAR APPLICATIONS .REFRACTORY/ .EMI .5: .LOW .I .OVERLAY .METAL/ .P DESCRIPTION G OLD METALLIZATION T TER SITE BALLASTED 1 VSWR CAPABILITY THERMAL RESISTANCE NPUT/OUTPUT MATCHING GEOMETRY CERAMIC HERMETIC PACKAGE OUT = 14.5 W MIN. WITH 8.6 dB GAIN .310 x .310 2LFL (S064) hermetically sealed ORDER CODE AM 81214-015 BRANDING 81214-15 PIN CONNECTION The AM81214-015 device is a high power Class C transistor specifically designed for L-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 is capable of withstanding 5:1 output VSWR at rated RF conditions. Low RF thermal resistance and computerized automatic wire bonding techniques ensure high reliability and product consistency. AM81214-015 is supplied in the grounded IMPACTM Hermetic Metal/Ceramic package with internal input/output matching structures. ABSOLUTE MAXIMUM RATINGS (T case = 25 C) Symbol Parameter Value Unit 1.
