Patent attributes
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 dual-transmit mode. The electronic device includes the multiway switch, a radio frequency circuit, and an antenna system. The multiway switch includes four T ports and 2n P ports. The four T ports are configured to be coupled with the radio frequency circuit. The 2n P ports are configured to be coupled with the antenna system. The four T ports include two first T ports 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 2n antennas of the antenna system corresponding to the 2n P ports in turn.
