GENERAL DESCRIPTION
CASE OUTLINE
55KT FET
(Common Gate)
The 0150SC-1250M is a Common Gate N-Channel Class AB SILICON
CARBIDE STATIC INDUCTION TRANSISTOR (SIT) capable of
providing 1250 Watts minimum of RF power from 150 to 160 MHz. The
transistor is designed for use in High Power Amplifiers supporting applications
such as VHF Weather Radar and Long Range Tracking Radar. The device is
the first in a series of High Power Silicon Carbide Transistors from
Microsemi PPG.
