A radio frequency (RF) signal transceiver is provided. The RF signal transceiver includes a first transformer, a signal transceiving processor, a signal receiving amplifier, and a signal transmitting amplifier. The first transformer is coupled to an antenna through a first end of a primary side, and two endpoints of a secondary side of the first transformer receive and transmit a pair of differential signals. The signal transceiving processor receives a pair of input differential signals from the secondary side of the first transformer and generates a pair of processed differential signals. The signal receiving amplifier is coupled to the signal transceiving processor and is configured to receive and amplify the pair of processed differential signals. The signal transmitting amplifier is coupled to the secondary side of the first transformer and provides a pair of transmission differential signals to the secondary side.
