Abstract

A multiway switch, a radio frequency system, and a wireless communication device are provided. The multiway switch includes eight T ports and four P ports. The eight T ports includes four first T ports and each of the four first T ports is coupled with all of the four P ports. The four first T ports support a transmission-reception function. The multiway switch is configured to be coupled with a radio frequency circuit and an antenna system of an electronic device to implement a preset function of the electronic device. The antenna system includes four antennas corresponding to the four P ports. The preset function is a function of transmitting a sounding reference signal (SRS) through the four antennas in turn.
