  • Wireless device and method for performing antenna tuner updates that minimizes adverse effects on transmit and receive channels
    Patent number: 9300332
    Abstract: A wireless device performs antenna tuner updates at times that minimize adverse effects on transmit and receive channels of the wireless device. The wireless device includes an antenna, an RF front end, an antenna tuner circuit and a processing module. The antenna tuner circuit is configured to substantially match a source impedance of the RF front end to a load impedance of the antenna based on a control signal. The processing module is configured to identify an update time for providing the control signal to the antenna tuner circuit that minimizes adverse effects on at least one of the transmit channel and the receive channel.
