  • Method and system of MIMO and beamforming transmitter and receiver architecture
    Patent number: 9144012
    Abstract: A multiple-input multiple-output (MIMO) receiver includes a receive path circuitry configured to receive a first signal from a first antenna and a second signal from a second antenna, downconvert the first signal to a first frequency to generate a first intermediate frequency (IF) signal, downconvert the second signal to a second frequency different from the first frequency to generate a second IF signal, and combine the first IF signal and the second IF signal into a common signal.
    Type: Grant

  • Method of power amplifier predistortion adaptation using compression detection
    Patent number: 8620233
    Abstract: A method of power amplifier predistortion that makes use of a compression detector circuit in a feedback loop in order to adapt the channel gain for changing transmitter behavior. By monitoring the compression behavior of the amplifier, the signal is scaled to compensate for gain and compression point variations in the power amplifier and transmitter, while keeping a predistortion correction function constant.

  • Tunable power amplifier using laminate MEMS capacitors
    Patent number: 8502608
    Abstract: For use in a wireless network, a tunable power amplifier circuit includes a power amplifier transistor and a plurality of laminate MEMS (microelectromechanical system) capacitors coupled to the power amplifier transistor. The laminate MEMS capacitors are arranged in a tunable matching network and configured to provide a matching impedance for the power amplifier transistor. In some embodiments, the laminate MEMS capacitors are arranged in a binary array.
