DESCRIPTION:
The MS2272 avionics power transistor is a broadband, high peak
pulse power device specifically designed for avionics
applications requiring broad bandwidth with moderate duty cycle
and pulse width constraints such as ground/ship DME/TACAN.
The MS2272 is also designed for specialized applications where
reduced power is provided under pulse formats utilizing short
pulse widths and high burst or overall duty cycles. This device is
capable of withstanding 15:1 VSWR mismatch load conditions at
any phase angle under full rated conditions.
