PRELIMINARY
CGH35015F
15 W, 3300-3900 MHz, 28V, GaN HEMT for WiMAX
Cree’s CGH35015F is a gallium nitride (GaN) high electron mobility
transistor designed specifically for 802.16-2004 WiMAX Fixed Access
applications. GaN HEMTs offer high efficiency, high gain and wide
bandwidth capabilities, which makes the CGH35015F ideal for 3.3-3.9GHz
www.DataSheeWt4UiM.cAomX and BWA amplifier applications. The transistor is available in a
flange package.
