DESC RIPT ION
The AM1214-175 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 is capable of withstanding 3:1 output
VSWR at rated RF conditions. Low RF thermal
resistance and computerized automatic wire bonding techniques ensure high reliability and product
consistency.
The AM1214-175 is supplied in the BIGPAC Hermetic M etal/ Cerami c package wi th i nternal
Input/Output matching structures.
