Abstract
This paper presents the design scheme of a passive intermodulation distortion (PIMD) finder in order to find out the birthplace of PIMD which is introduced by sharing a feeder cable in in-building wireless multi-band networks. To this end, a frequency-modulated continuous-wave (FMCW) signal generation module and a fast Fourier transform (FFT)-based signal processing module are implemented to figure out the exact PIMD occurrence point. By improving the common feeder cable conditions with the timely PIMD detection, mobile consumer devices are expected to be well operated in in-building without call drop due to the PIMD.
