Multi-way switch, radio frequency system, and wireless communication device

A radio frequency system, comprising an antenna system, a radio frequency circuit, and a multi-way switch coupled with the radio frequency circuit and the antenna system of a wireless communication device;

• the multi-way switch comprising five T ports and four P ports, and the five T ports comprising two first T ports and three second T ports, each first T port being coupled with all of the four P ports and each second T port being coupled with one corresponding P port of the four P ports;
• the wireless communication device operable in a dual-frequency single-transmit mode;
• the antenna system comprising four antennas corresponding to the four P ports;
• and
• the multi-way switch being configured to implement a preset function of transmitting the SRS through the four antennas in turn;
• wherein the three second T ports support reception at a first frequency band and a second frequency band, wherein the first frequency band does not overlap with the second frequency band;
• the three second T ports are coupled with different P ports;
• the four P ports are coupled in one-to-one correspondence with the four antennas;
• and
• the two first T ports comprise one first T port supporting transmission and reception at the first frequency band and the other first T port supporting transmission and reception at the second frequency band.
