Latest Patents
Zhijun Chen's latest patents include an antenna switching circuit and electronic device. This invention features a radio frequency processor, a radio frequency front-end, a first switch, and an antenna system with multiple antennas. The radio frequency processor receives a first radio frequency signal, generates a second radio frequency signal based on the loss value of the first switch, and transmits this signal to the first switch. The first switch selects a radio frequency channel from the radio frequency front-end and transmits the second radio frequency signal accordingly. The radio frequency front-end processes the second radio frequency signal to generate a third radio frequency signal, which is then output by the antenna system. Another notable patent involves a method and apparatus for controlling radio frequency exposure of wireless devices. This method includes obtaining an average radio frequency exposure value over a target time window, determining a corresponding power threshold, and controlling the transmit power of the wireless device based on this threshold.
