A High Linearity, High Efficiency WiMAX Power Amplifier Using SiC MESFETs

Date: January 2008
Type: White Paper
Rating: (0)

Overview: This research paper published by WiMAX describes the results of a broadband, high linearity and high efficiency power amplifier for WiMAX basestation applications in the 3.3 - 3.9 GHz band. Using SiC MESFETs, a single-stage power amplifier has been designed that provides a significant increase in performance, providing 17% drain efficiency, 1.5% EVM, and 3dB margin to spectral mask at 1.5W average output power under a WiMAX compliant signal, compared with realizations using other transistor technologies.
