DESCRIPTION
The AM81214-030device is a high power transistor specifically designed for L-Band Radar pulsed driver applications.
The device is capable of operation over a wide range of pulse widths,duty cycles and tempera-tures and is capable of withstanding ∞:1output VSWR at rated RF conditions.Low RF thermal resistance and computerized automatic wire bond-ing techniques ensure high reliability and product consistency.
The AM81214-030is supplied in the IMPAC ?Her-metic Metal/Ceramic package with internal Input/Output matching structures.
