Includes bibliographical references. "This report details an investigation concerning passive intermodulation (PIN) interference generation in UHF (200 - 400 MHz) satellite communication systems. A survey of reported phenomena which can generate PIM is presented. Analytical techniques for the calculation of intermodulation signal powers are reviewed and a novel technique is proposed. A combination of theoretical analysis and experiments with two transmit frequencies is then applied in an investigation concerning the identification of PIN signal sources by power response signatures. A study of the vacuum phenomenon of multifactor breakdown, a known PIN generator, is also reported"--Abstract. gccst Satellites gccst Telecommunications Chudobiak, W. J., author.
