DESCRIPTI ON
The MSC81035M is a medium power Class C
transistor designed specifically for pulsed L-Band
avionics applications. This device is a direct replacement for the MSC1035M. MSC81035M 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 MSC8103 5M is housed in t he IMPAC
package with internal input matching.
