DESCRIPTION

The MSC81250M device is a high power pulsed

transistor specifically designed for DME/TACAN

avionics applications.

This device is capable of withstanding a minimum

20:1 load VSWR at any phase angle under full

rated conditions. Low RF thermal resistance and

semi automatic wire bonding techniques ensure

high reliability and product consistency.

The

MSC81250M

is

housed

in

the

unique

AMPAC

™ package with internal input/output

matching structures.
