Abstract: A wireless terminal and an antenna switching control method for a wireless terminal, where the wireless terminal includes a main antenna, a first antenna, and a second antenna. The main antenna is connected to a first radio frequency circuit and configured to receive and transmit a first standard signal. A frequency band of the first standard signal includes a first frequency band with a super high frequency and a second frequency band with a high frequency. The first antenna is configured to receive a first standard signal of the first frequency band, and receive and transmit a second standard signal. The second antenna is connected to the first radio frequency circuit and configured to receive a first standard signal of the second frequency band. Hence an overall size of the wireless terminal can be reduced using the second antenna.

Abstract: An circuit board assembly includes a first circuit board, a second circuit board stacked with the first circuit board, and a connection plate connected between the first circuit board and the second circuit board. The connection plate includes a signal transmission part and at least one ground part at a spacing to the signal transmission part. The ground part can be used as a reference ground for a signal transmitted by the signal transmission part, so that the characteristic impedance of the signal transmission part is controllable, and the signal transmitted by the signal transmission part has strong continuity, thereby maintaining good matching performance and reducing an insertion loss caused by characteristic impedance mismatch.

Abstract: A method includes obtaining an average radio frequency exposure value over a target time window, where the target time window is a standard time window, determining a power threshold corresponding to the average radio frequency exposure value, where the power threshold is a preset power value corresponding to a preset value range to which the average radio frequency exposure value belongs, and controlling a transmit power of the wireless device based on the power threshold over a controlled time window.

Abstract: An antenna switching circuit, electronic device and method. The switching circuit includes a radio frequency processor, a radio frequency front-end, a first switch, and an antenna system with a plurality of antennas. The radio frequency processor receives a first radio frequency signal, generates a second radio frequency signal based on a loss value of the first switch, and transmits the second radio frequency signal to the first switch. The first switch selects, from a plurality of radio frequency channels in the radio frequency front-end, a radio frequency channel coupled with the radio frequency processor, and transmits the second radio frequency signal to a radio frequency channel. The radio frequency front-end receives and processes the second radio frequency signal to generate a third radio frequency signal and transmits it to the antenna system, which outputs the third radio frequency signal.
