PRELIMINARY SPECIFICATION
GENERAL DESCRIPTION
The 0405SC-1000M is a Common Gate N-Channel Class AB SILICON
CARBIDE STATIC INDUCTION TRANSISTOR (SIT) capable of
providing 1000 Watts of RF power from 406 to 450 MHz. The transistor is
designed for use in High Power Amplifiers supporting applications such as UHF
Weather Radar and Long Range Tracking Radar. The device is an addition to
a series of High Power Silicon Carbide Transistors from Microsemi PPG.
