DESCRIPT ION
The AM2729-110 device is a high power silicon
bipolar NPN transistor specifically designed for SBand radar pulsed output and driver applications.
This device is capable of operation over a wide
range of pulse widths, duty cycles and temperatures and can withstand a 3:1 output VSWR. Low
RF thermal resistance, refractory/gold metallization, and computerized automatic wire bonding
techniques ensure high reliability and product consistency (including phase characteristics).
The AM2729-110 is supplied inthe BIGPAC Hermetic Metal/ Cerami c package wi th i nternal
Input/Output matching circuitry, and is intended
for military and other high reliability applications.
