Abstract
An embodiment of a low power system for measuring passive intermodulation (PIM) includes a port, a test signal source, a dielectric frequency domain multiplexer and a receiver. The test signal source provides 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. The dielectric frequency domain multiplexer connected with the port and the test signal source and is adapted to multiplex the test signal provided by the test signal source and a measurement signal obtained at the port. The receiver receives the multiplexed measurement signal from the dielectric frequency domain multiplexer and provides a signal indicative of PIM.
