Abstract
A multiway switch, a radio frequency system, and a wireless communication device are provided. The multiway switch includes four T ports and 2n P ports. The four T ports include two first T ports and each of the two first T ports is coupled with all of the 2n P ports. n is an integer and n≥2. The multiway switch is configured to be coupled with a radio frequency circuit and an antenna system of a wireless communication device operable in a dual-frequency dual-transmit mode, to implement a preset function of the wireless communication device, the antenna system includes 2n antennas corresponding to the 2n P ports, and the preset function is a function of transmitting a sounding reference signal (SRS) through the 2n antennas in turn.
