<p>PURPOSE: An apparatus for measuring a transceiving power gain of a remote RF(Radio Frequency) unit in a micro base station is provided to facilitate a state check of the remote RF unit in a main base station and to detect in itself whether or not a sub unit is malfunctioning measuring the transceiving power gain of the remote RF unit in the micro base station which is composed of the main base station and sub unit like the remote RF unit. CONSTITUTION: A transceiving power gain measurement apparatus of a remote RF unit includes a base band(100), an RF unit(200), a remote RF unit(300). The base band(100) generates an IF signal and measures the gain of transceiving power. The RF unit(200) converts the IF signal input from the base band(100) to an RF signal and outputs the RF signal. The remote RF unit(300) transmits the RF signal input from the RF unit(200) to the base station and a terminal or receives the RF signal from the exterior. Besides, the remote RF unit(300) switches the RF signal in order that the base band(100) enables to measure the gain of transceiving power.</p> |
