DESCRIPTION:
The
672-
1175M 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.
