PRELIMINARY SPECIFICATION
GENERAL DESCRIPTION
The 0405SC-1500M is a Common Gate N-Channel DEPLETION MODE
Class AB SILICON CARBIDE (SiC) STATIC INDUCTION
TRANSISTOR (SIT) capable of providing 1500 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.
