DESCRIPTION
The AM2729-110 device is a high power silicon bipolar NPN transistor specifically designed for S- Band radar pulsed output and driver applications. This device is capable of operation over a wide range of pulse widths, duty cycles and tempera- tures and can withstand a 3:1 output VSWR. Low RF thermal resistance, refractory/gold metalliza- tion, and computerized automatic wire bonding techniques ensure high reliability and product con- sistency (including phase characteristics). The AM2729-110 is supplied in the BIGPAC Her- metic Metal/Ceramic package with internal Input/Output matching circuitry, and is intended for military and other high reliability applications.
