DESCRIPTION
The AM82731-006 device is a medium power silicon
bipolar NPN transistor specifically designed for SBand radar pulsed driver applications.
This device is capable of operation over a wide range
of pulse widths, duty cycles, and temperatures and
can withstand a 5:1 output VSWR. Low RF thermal
resistance, refractory/gold metallization, and automatic wire bonding techniques ensure high reliability
and product consistency.
The AM82731-006 is supplied in the hermetic metal/ceramic package with internal input/output impedance matching circuitry, and is intended for military
and other high reliability applications.
