Abstract :
Passive intermodulation (PIM) occurring in multicarrier transmission systems can have deleterious effects on system performance by significantly increasing the noise level. An argument is presented for system-level testing for PIM, particularly for high-power communications satellites. In the past, two-carrier, component-level tests were employed to ensure that PIM would not degrade system S/N performance.
