    Abstract: A wireless communication calibration system has a radio chipset, an analog circuit set, and a calibration path. The radio chipset has a transmitter and a receiver. The analog circuit set is external to the radio chipset and coupled to the transmitter, and receives an output signal of the transmitter and generates a transmission signal according to the output signal. The calibration path is external to the radio chipset and coupled to the analog circuit set, and guides an input signal to the receiver, wherein the input signal is derived from the transmission signal, and a first delay is calculated after the input signal is received by the receiver.
