| MSC81035MP RF & MICROWAVE TRANSISTORS AVIONICS APPLICATIONS .REFRACTORY/ .EMI . .LOW .I .OVERLAY .METAL/ .P DESCRIPTION G OLD METALLIZATION T TER SITE BALLASTED :1 VSWR CAPABILITY THERMAL RESISTANCE N PUT MATCHING GEOMETRY C ERAMIC HERMETIC PACKAGE OUT = 35 W MIN. WITH 10.7 dB GAIN .280 4LSL (S051) epoxy sealed ORDER CODE MSC81035MP BRANDING 81035MP PIN CONNECTION The MSC81035MP is a medium power Class C transistor designed specifically for pulsed L-Band avionics applications. This device is a direct replacement for the MSC1035MP. MSC81035MP offers improved saturated ouput power and collector efficiency based on the test circuit described herein. Low RF thermal resistance and computerized automatic wire bonding techniques ensure high reliability and product consistency. The MSC81035MP is housed in the IMPACTM package with internal input matching. ABSOLUTE MAXIMUM RATINGS (T case = 25 C) Symbol Parameter Value Unit 1. Collector 2. Base 3. Emitter 4.
