Patent ID: 7076213

Claim:
An apparatus for testing a voltage standing wave ratio (VSWR) in a wideband code division multiple access (W-CDMA) mobile communication system, the apparatus comprising: a controller for determining, upon detecting a VSWR test request, oscillation frequency information and a power level information of a test signal for a VSWR test, and generating a test signal generation request including the determined oscillation frequency information and power level information, wherein the controller selects two arbitrary frequency assignments (FAs) employed in the W-CDMA mobile communication system, and defines a frequency between center frequencies of the two selected FAs as the oscillation frequency information; a test signal generator for generating, upon detecting the test signal generation request, a test signal corresponding to the oscillation frequency information and 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 a voltage standing wave ratio using the received test signal and reflected signal.
