Abstract:
1. A compact, low power system for measuring passive intermodulation (PIM), comprising: a port; a test signal source providing a test signal including two tones each capable of producing a signal at the test port of amplitude +30 decibels referenced to one milliwatt (dBm) or less; a dielectric frequency domain multiplexer connected with the port and the test signal source; wherein the test signal source is moreover prevented from producing a signal having an output power above the operating limit of the dielectric frequency domain multiplexer; wherein the dielectric frequency domain multiplexer is adapted to multiplex the test signal provided by the test signal source and a measurement signal obtained at the port; a receiver to receive the multiplexed measurement signal from the dielectric frequency domain multiplexer; wherein the receiver has an output that provides a signal indicative of PIM.
