Apparatus and method for testing voltage standing wave ratio in a W-CDMA mobile communication system

An apparatus for testing a voltage standing wave ratio (VSWR) in a wideband coded division multiple access (W-CDMA) mobile communication system employing a plurality of frequency assignments (FAs), the apparatus comprising:

• a controller for defining, upon detecting a VSWR test request, an oscillation frequency information of a test signal for a VSWR test as a frequency between center frequencies of two arbitrary FAs among the plurality of FAs, determining a power level information of the test signal, and generate a test signal generation request that includes the determined oscillation frequency information and the power level information;
• a test signal generator for generating, upon detecting the test signal generation request, a test signal corresponding to the oscillation frequency information and the power level information, and providing the generated test signal to an antenna;
• and
• a VSWR detector for receiving the test signal and a reflected signal of the test signal from the antenna, and calculating the VSWR using the received test signal and the reflected signal.
