DESCRIPTION
The AM1214-200 device is a high power Class
C transistor specifically designed for L-Band Radar
pulsed output and driver applications.
This device is capable of operation over a wide
range of pulse widths, duty cycles and temperatures, and wiil tolerate severe mismatch and overdrive conditions. Low RF thermal resistance and
computerized automatic wire bonding techniques
ensure high reliability and product consistency.
AM1214-200 is supplied in the BIGPAC hermetic
metal/ceramic package with internal input/output
matching structures.
