The problem of passive intermodulation (PIM), whereby carrier frequencies are modified through combination with their harmonics, is being investigated by researchers at Queen’s University Belfast. PIM is an issue particularly in cellular basestations, which suffer from the effect due to the large difference between transmitted and received power. Basestation antenna designers have to meet a requirement that the harmonics are ...
