DESCRIPTION:
The MS2221 is a high power transistor specifically designed
for L–Band radar pulsed output and driver applications.
This device is designed for operation under moderate pulse
width and duty cycle pulse conditions. Internal impedance
matching provides optimum performance across the entire
frequency band.
