  • Low-noise highly-linear wideband vector modulators
    Patent number: 11750427
    Abstract: Vector modulation is illustrated. A method includes receiving an input signal. The input signal is split into a first 0° output and a 90° output. The first 0° output is split into a second 0° output and a first 180° output using a continuous transmission line. The 90° output is split into a third 0° output and a second 180° output using a continuous transmission line. The second 0° output, the first 180° output, the third 0° output, and the second 180° output are modulated. The modulated second 0° output, the first 180° output, the third 0° output, and the second 180° output are recombined to produce an output signal, where all four of the modulated second 0° output, the first 180° output, the third 0° output, and the second 180° output are used to create the output signal.

  • Adaptive filtering for canceling distortion in radio frequency signals
    Patent number: 9344122
    Abstract: Adaptive filtering is used to substantially cancel distortion in radio frequency (RF) signals. Such adaptive filtering can be used in an RF transmitting module to pre-compensate an RF signal with compensation (inverse) distortion to cancel inherent transmission path distortion from the RF signal. Adaptive filtering can also be used in a multi-carrier RF receiving module to cancel from a given carrier signal distortion due to cross talk from adjacent carrier signals. Adaptive filtering in an RF transceiver can be used to cancel from a received RF signal distortion arising from leakage of a transmit signal into the receive path.
