DESCRIPTION
The AM1214-325 device is a high power transistor specifically designed for L-Band radar pulsed out- put and driver applications. This device is designed for operation under moder- ate pulse width and duty cycle pulse conditions and is capable of withstanding 5:1 VSWR at rated RF conditions. Low RF thermal resistance and computerized automatic wire bonding techniques ensure high reliability and product consistency. The AM1214-325 is supplied in the BIGPAC Her- metic Metal/Ceramic package with internal Input/Output matching structures.
