DESCRIPTION
The AM82731-012 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 operaion over a wide
range of pulse widths, duty cycles, and tempera-
tures and can withstand a 3:1 output VSWR with
a + 1 dB input overdrive. Low RF thermal resist-
ance, refractory/gold metallization, and automatic
wire bonding techniques ensure high reliability and
product consistency (including phase charac-
teristics).
The AM82731-012 is supplied in the Hermetic Met-
al/Ceramic package with internal Input/Output im-
pedance matching sircuitry, and is intended for
military and other high reliability applications.
