DESCRIPTION:
DESCRIPTION:
The MSC1175M 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 20:1 load
VSWR at any phase angle under full rated conditions. Internal
impedance matching provides consistent broadband performance.
