Abstract
A signal transmitting/receiving circuit includes a transmitter, a receiver, a balun and an impedance matching circuit. The transmitter is utilized for transmitting an output signal. The receiver is utilized for receiving an input signal. The balun includes a first input terminal, a second input terminal and an output terminal. The impedance matching circuit, which is coupled between the transmitter, the receiver, and the balun, provides transmitting impedance when the transmitter transmits the output signal such that an output signal may be output at an output terminal of the balun via a transmitting path. Also, the impedance matching circuit provides transmitting impedance when the receiver receives the input signal such that the input signal may be transmitted from the output terminal of the balun to the receiver via a receiving path.
