CGHV14800
800 W, 1200 - 1400 MHz, 50 V, GaN HEMT for L-Band Radar Systems
Cree’s CGHV14800 is a gallium nitride (GaN) high electron mobility transistor (HEMT) designed
specifically with high efficiency, high gain and wide bandwidth capabilities, which makes the
CGHV14800 ideal for 1.2 - 1.4 GHz pulsed L-Band radar amplifier applications, such as air traffic
control (ATC) radar, weather radar, penetration radars, antimissile system radars, target tracking
radars and long range survelliance radars. The GaN HEMT typically operates at 50 V, typically
deliverying >65% drain efficiency. The package options are ceramic/metal flange package.
