Switch Solutions For Systems With Low PIM RequirementsSource: Dow-Key Microwave Corp.
The effect of nonlinearities is becoming more prominent in signals with higher amplitude as it results into intermodulation levels that are more evident. These signals interfere with the desired system behavior and causes unwanted results. In order to reduce intermodulation in passive devices, low PIM designs are required. This paper will focus on defining Passive Intermodulation (PIM) and the concerns around PIM, the cause of PIM in both general terms and in switches, and present a solution for systems with Low PIM requirements.
