A radio-frequency circuit includes an antenna connection terminal, switch circuits, a duplexer, a low-pass filter, and a high-pass filter. The switch circuit includes a port connected to the antenna connection terminal and ports. The switch circuit includes a single transmission port connected to the port, a simultaneous transmission port connected to ports. The duplexer is connected to the port. The low-pass filter is disposed on a signal path connecting the port and the simultaneous transmission port. The high-pass filter is connected to the port. No filter is disposed on a signal path connecting the port and the single transmission port.
