Patent ID: 10615838

Abstract:
A multiway switch, a radio frequency system, and an electronic device are provided. The multiway switch is applicable to an electronic device being operable in a single-frequency single-transmit mode. The electronic device includes the multiway switch, a radio frequency circuit and an antenna system. The antenna system includes 2n antennas. The multiway switch includes four T ports and 2n P ports. The four T ports are configured to be coupled with the frequency circuit. The 2n P ports are configured to be coupled with the antenna system. The four T ports include one first T port coupled with all of the 2n P ports. The multiway switch is configured to be coupled with the radio frequency circuit and the antenna system to implement a preset function of transmitting a sounding reference signal (SRS) through the 2n antennas corresponding to the 2n P ports in turn.
