CGH35015

15 W, 3300-3900 MHz, 28V, GaN HEMT for WiMAX

Cree’s CGH35015 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 CGH35015 ideal for 3.3-3.9GHz WiMAX and BWA amplifier applications. The transistor is available in both screw-down, flange and solder-down, pill packages.

Features:

  • 3.3 - 3.9 GHz Operation
  • 15 W Peak Power Capability
  • 12 dB Small Signal Gain
  • 2.0 W PAVE at < 2.0 % EVM
  • 26 % Efficiency at 2 W Average Power
  • WiMAX Fixed Access 802.16-2004 OFDM
  • WiMAX Mobile Access 802.16e OFDMA
