DESCRIPTION
The AM83135-015 device is a high power silicon
bipolar NPN transistor specifically designed for
S-Band radar pulsed output and driver applica-
tions.
This device is characterized at 100
sec pulse
width and 10% duty cycle, but is capable of op-
eration over a range of pulse widths, duty cycles,
and temperatures, and can withstand a 3:1 out-
put VSWR with a + 1 dB input overdrive. Low RF
thermal resistance, refractory/gold metallization,
and computerized automatic wire bonding tech-
niques ensure high reliability and product consis-
tency (including phase characteristics).
The AM83135-015 is supplied in the IMPACTM
Hermetic Metal/Ceramic package with internal
Input/Output impedance matching circuitry, and
is intended for military and other high reliability
applications.
