DESCRIPTIO N

The AM0912-300 avionics power transistor is a
broadband, high peak pulse power device speci­fically designed for avionics applications requiring
broad bandwidth with moderate duty cycle and
pulse width constraints such as ground/ship based
DME/TACAN.

The AM0912-300 is also designed for specialized
applications where reduced power is provided
under pulse formats utilizing short pulse widths
and high burst or overall duty cycles.

This device is capable of withstanding 15:1 VSWR
mismatch load condition at any phase angle under
full rated conditions.

The AM0912-300 is housed in the unique BIG­PAC Hermetic Metal/Ceramic package with in­ternal Input/Output matching structures.
