ORDER CODE
DESCRIP TIO N
The AM2729-125 device is a high power silicon
bipolar NPN transistor specifically designed for
medium pulse S-Band radar output and driver
applications.
This device is characterized at 50 µsec pulse
width and 10% duty cycle, but is capable of operation over a range of pulse widths, duty cycles
and temperatures. Low RF thermal resistance,
refractory/gold metallization and computerized
automatic wire bonding techniques ensure high
relia b ilit y and product consiste n cy (inclu d in g
phase characteristics).
The AM2729-125 is supplied in the BIGPAC
Hermetic Metal/Ceramic package with internal Input/Output impedance matching circuitry, and is
intended for military and other high reliability applications.
