DESCRIPTION:
The MS2228 device is a high power Class C transistor specifically
designed for L-Band Avionics transponder/interrogator pulsed
output and driver applications.
This device is capable of operation over a wide range of pulse
widths, duty cycles, and is capable of withstanding 10:1 output
VSWR at rated RF conditions. Internal input and output matching
provide optimum performance and product consistency.
