CGHV14800
800 W, 960 - 1400 MHz, 50 V, GaN HEMT for
L-Band Radar Systems
Description
The 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 960 - 1400 MHz 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 delivering
> 65% drain efficiency. The GaN HEMT comes in a ceramic/metal flange package.
