The advent of wireless with its tightly grouped, high power, high frequency signals and the associated high sensitivity receivers has created many unanticipated PIM (Passive Intermodulation) problems. PIM is caused by improper design of the passive, sharing  transmission line by the receive signal. This brief overview describes a few of the problems and solutions encountered by Microlab/FXR in its efforts to supply PIM-free wireless components.
