Carrier power dependence and avoidance methods of passive intermodulation product

Abstract

With the widely development of high power and multi-channel system, passive intermodulaton (PIM) caused by passive components can not be neglected anymore. In this paper, an experimental investigation of the relationship between PIM levels and the carrier powers has been carried out and the results are reported and fitted. Then the performance requirement of passive component used in wireless system is introduced and frequency planning method to avoid effective hit of PGSM is provided.
