Passive Intermodulation (PIM) has been with us since the beginning of radio; so why is it now important? Simply put the answer is NOISE! Radio noise often called the noise floor puts ear muffs on radio receivers reducing their ability to capture small signal levels. With the rapid move to LTE and other data rich wireless applications the impact of noise has received a great deal of attention. This presentation will provide a short overview of why PIM at long last is getting its due attention. The primary sources of PIM, along with a detailed discussion of internal vs. external PIM will be defined. How we can test for it in all radio bands? More importantly, how can it be mitigated? Questions from the audience specific to problems found at radio sites are encouraged.
