PURPOSE: A method for unifying the calibration process of a transceiver is provided to enable the transceiver to always hold its own calibration data, by installing peripheral devices, such as a read-only memory, digital-to-analog converter and a transistor-to-transistor logic, to a transceiver board. CONSTITUTION: A calibration program in a personal computer is executed in order to control the operation of an automatic phase controller of an analog wave(S1). An enable terminal is controlled using a next chip after the execution of the calibration program(S2). With the control of the enable terminal, data is transferred to the digital-to-analog converter(S3). The data is applied to the automatic phase controller via a buffer circuit(S4). The personal computer receives the values of output voltages in response to the data applied to the automatic phase controller(S5). The personal computer writes the received values in the read-only memory(S6).
