DESCRIPTION
The AM83135-030 device is a high power silicon 
bipolar NPN transistor specifically designed for SBand radar pulsed output and driver applications.
This device is characterized at 100µsec pulse 
width and 10% duty cycle, but is capable of operation over a range of pulse widths, duty cycles, 
and temperatures, and withstand a 3:1 output 
VSWR with a + 1 dB input overdrive. Low RF 
thermal resistance, refractory/gold metallization, 
and computerized automatic wire bonding techniques ensure high reliability and product consistency (including phase characteristics).
The AM83135- 030 is supp lied in the IMP AC™ Hermetic Metal/Ceramic package with internal 
Input/Output impedance matching cir cuitry, and is 
intended for mili tary and other high reliability applications.
