A radio frequency (RF)-based communication terminal includes a first switching chip, a second switching chip, a comparison module, a low noise amplifier (LNA), a first filter, a power amplifier (PA), a second filter, and a control module. The comparison module compares the power of a radio signal Rx received from a base station with a pre-stored signal and to output a control signal according to the comparison result. The control module controls conductive modes of the first and the second switching chips according to the control signal. In the first conductive mode, a radio signal Tx is sent out from the PA and the second filter. In the second conductive mode, the radio signal Tx is exchanged to send out from the LNA and first filter.

Radio frequency-based communication terminal having two exchangeable transmitting paths

A wireless communication device includes an antenna module, a transceiving module, and a switch module. The antenna module includes a first antenna and a second antenna. The transceiving module includes a first transceiver and a second transceiver. The switch module switches different connections between the antenna module and the transceiving module, and includes a first single-pole-double-throw (SPDT) switch, a second SPDT switch, a third SPDT switch, a first duplexer, a second duplexer, and a double-pole-double-throw (DPDT) switch.
