PURPOSE: A transceiver unit testing device using a PLL-jig in a mobile communication base station system is provided to reduce the expenses for maintenance works by testing a transceiver unit without an RF control unit or a notebook. CONSTITUTION: A power supply unit(100) supplies power to a clock generation unit(300), a memory(400) and a control unit(500). In case that an operator selects a driving mode, a key input unit(200) outputs a driving selection signal to the clock generation unit(300) and the control unit(500). After receiving the driving signal from the key input unit(200), the clock generation unit(300) outputs the clock to the control unit(500). The memory(400) stores PLL testing driving programs and testing output frequencies. The control unit(500) receives the driving selection signal from the key input unit(200). In addition, the control unit(500) transmits driving clocks to a PLL in a transceiver unit(10). A display unit(600) receives a test display control signal from the control unit(500).
