CREE CGH27060F

PRELIMINARY
CGH27060F
60 W, 2300-2900 MHz, 28V, GaN HEMT for WiMAX
Cree’s CGH27060F is a gallium nitride (GaN) high electron mobility transistor
(HEMT) designed specifically for high efficiency, high gain and wide bandwidth
capabilities, which makes the CGH27060F ideal for 2.3-2.9GHz WiMAX and
BWA amplifier applications. The transistor is supplied in a ceramic/metal
flange package.
