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
effic iency based on the test circuit described
herein.
Low RFthermal resistance and computerized automatic wire bonding techniques ensure high reliability and product consistency.
The MSC81035MP ishoused inthe IMPAC package with internal input matching.
