Abstract
A gallium nitride (GaN) radio frequency integrated circuit (RFIC) is configured to receive and amplify a low-level WiFi signal to generate a WiFi transmit signal. By using a GaN RFIC, the performance of the RFIC is significantly improved when compared to conventional RFICs for WiFi signals. In one exemplary embodiment, the RFIC has an error vector magnitude less than 29 dBc, an average power output around 29 dBm, and an average power added efficiency of greater than 25%. In additional embodiments, the RFIC has a gain greater than about 32 dB and a peak output power around −37 dB.
