  • Frequency domain multiplexer
    Patent number: 9401798
    Abstract: An apparatus includes an antenna, a first transceiver circuit, a second transceiver circuit, a first filter coupled between the antenna and the first transceiver circuit and configured to pass a first signal and attenuate a second signal, and a second filter coupled between the antenna and the second transceiver circuit and configured to pass the second signal and attenuate the first signal. The first signal has a first frequency and the second signal has a second frequency. The first transceiver circuit, the second transceiver circuit, and the first filter are integrated in a system on chip (SOC).

  • Power amplifier with wide band AM-AM feedback and digital pre-distortion
    Patent number: 9385666
    Abstract: A system including an amplifier circuit configured to amplify an input and generate an output, a bias circuit configured to bias the amplifier circuit, and a feedback circuit configured to generate feedback based on the input and the output, and to adjust the bias of the amplifier circuit based on the feedback to reduce amplitude nonlinearity in the output. A digital pre-distortion circuit is configured to reduce phase nonlinearity in the output.
