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.

Abstract: A microwave integrated circuit includes a substrate and a power amplifier on the substrate. The power amplifier includes a power divider circuit having an input configured to receive an input RF signal, a base amplifier having an input coupled to a first output of the power divider circuit and a peaking amplifier having an input coupled to a second output of the power divider circuit and an output coupled to an output combining node. The power amplifier further includes an impedance inverter circuit coupling the output of the base amplifier to the output combining node and a load matching circuit having an input coupled to the output combining node and an output configured to be coupled to a load.
