Passive Intermodulation; Ultrasonic Transducer; Vibration Modulation
“In Section 1, passive intermodulation (PIM) is introduced and the mechanism of it is briefly explained. Then, the up-to-date PIM testing and source identification method in the industrial and academia worlds will be summarized.
The vibration modulation method for PIM source identification is proposed in Section 2. Different vibration sources were tested and compared, and the test results showed that the vibration modulation method is able to identify PIM source with good accuracy.
Section 3 outlines a special PIM source identification system built based on the vibration modulation system. The two subsystems, PIM receiver and PIM vibrator, are illustrated in detail.
In Section 4, PIM source identification tests were conducted on a base station antenna using the PIM source identification system. The experiment results show the system was able to pinpoint the PIM source accurately”--Abstract, page iii.
