CGHV14250
250 W, 1200 - 1400 MHz, GaN HEMT for L-Band Radar Systems
Cree’s CGHV14250 is a gallium nitride (GaN) high electron mobility transistor (HEMT) designed
specifically with high efficiency, high gain and wide bandwidth capabilities, which makes the
CGHV14250 ideal for 1.2 - 1.4 GHz L-Band radar amplifier applications. The transistor could
be utilized for band specific applications ranging from UHF through 1800 MHz. The package
options are ceramic/metal flange and pill package.
