CGH21240F

240-W, 1800 – 2300-MHz, GaN HEMT for WCDMA, LTE, WiMAX

Cree’s CGH21240F is a gallium-nitride (GaN) high-electron-mobility transistor (HEMT) designed specifically with high-efficiency, high-gain and wide-bandwidth capabilities, which makes the CGH21240F ideal for 1.8 – 2.3-GHz WCDMA and LTE amplifier applications. The transistor is supplied in a ceramic/metal flange package.

Features:

  • 1.8 - 2.3 GHz Operation
  • 15 dB Gain 
  • -35 dBc ACLR at 40 W PAVE
  • 33 % Efficiency at 40 W PAVE
  • High Degree of DPD Correction Can be Applied
