The present invention provides a transceiver for a radio frequency identification (RFID) reader. The transceiver includes an RF front end, a transmitting component, a receiving component, a power divider and a micro control unit (MCU). The power divider has three terminals. The first terminal of the power divider is connected to the transmitting component. The second terminal of the power divider is connected to the receiving component. The third terminal is connected to the RF front end. Moreover, the MCU is connected to the transmitting component and the receiving component, and generates a transmitted signal and receives a retrieved data. According to the present invention, the transceiver further includes an RF switch, a matching circuit and a receiving circuit.
