DESCRIPTION
The MSC81450M device is a high power pulsed
transistor specifically designed for IFF avionics
applications.
This device is capable of withstanding a minimum
25:1 load mismatch at any phase angle under full
rated conditions.
The MSC81450M is housed in the unique BIG-
PAC鈩?package with internal input/output match-
ing structures.
