Title: SYSTEM, METHOD AND MULTIPLEXER FOR TESTING RADIO FREQUENCY OF BASE STATION
Abstract:
The present invention provides a system, method and multiplexer for testing radio frequency of a base station. The multiplexer comprises: a first port connected to a radio frequency port to be tested of the base station; a first combiner connected to the first port; at least a second port connected to a radio frequency spectrum analyzer; at least a third port connected to a signal generator; a band-pass filter connected between the first combiner and the second port, and a passband of the band-pass filter is a downlink radio frequency signal frequency range of the base station; a band-stop filter connected between the first combiner and the third port, and a stopband of the band-stop filter is a downlink radio frequency signal frequency range of the base station. By applying the technical solutions provided by the present invention, the test efficiency of the radio frequency test of the LTE (Long Term Evolution) base station can be improved, the test cost can be reduced and the test result can be more accurate, and a simultaneous test of different frequency RRU (Radio Remote Unit) can be supported, and the multiplexer can implement the simplification of the test environment, improve the stability during the test and the reliability of the test result.
