Magnetic Passive Intermodulation Mitigation System
Purdue University researchers have developed two novel methods of reducing PID in a wireless system. The first method alters the magnetic properties of a connector containing steel or nickel. The result is a connector that has similar PID performance to gold or silver at a lower cost. The second method is a tunable PID cancellation system; the frequency, magnitude, and phase of the signal can be adjusted to precisely remove the unwanted distortion. Both methods can greatly enhance the spectral purity of a signal in a communication system.
