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
