Document Type and Number:

WIPO Patent Application WO/2016/108450

Kind Code:

A1

Abstract:

A remote apparatus comprises: a plurality of sub-amplification units for amplifying radio frequency (RF) signals in different frequency bands, respectively; a test signal generation unit for generating test signals in a frequency band for one of the plurality of sub-amplification units; a conversion unit for converting an intermodulation (IM) signal generated in response to the test signals into a plurality of converted IM signals, using a frequency-swept conversion signal; and a control unit for determining the degree of intermodulation distortion caused by the one sub-amplification unit on the basis of the signal levels of the plurality of converted IM signals.
