DESCRIPTION:
The MSC1400M is a NPN bipolar transistor specifically
designed for high peak pulse power applications such as
DME/TACAN.
This device is capable of withstanding a minimum 25:1 load
VSWR at any phase angle under full rated conditions.
Internal impedance matching provides consistent
broadband performance.
