s, 10%
S-Band Radar 2700 - 3100 MHz
GENERAL DESCRIPTION
The 2731GN-220V is an internally matched, COMMON SOURCE, class AB,
GaN on SiC HEMT transistor capable of providing over 10 dB gain, 220 Watts
of pulsed RF output power at 200uS pulse width, 10% duty factor across the
2700 to 3100 MHz band. This hermetically sealed transistor is designed for S-
Band Radar applications. It utilizes gold metallization and eutectic attach to
provide highest reliability and superior ruggedness.
Market Application – 2731GN-220V is designed for S-Band Pulsed Radar
