摘要：

A modified passive intermodulation (PIM) model with multiple nonlinear sources and lossy transmission is developed to evaluate the reflected passive intermodulation products (PIMP) in case of series connection. Equivalent circuit models are proposed for demonstrating the effect of length between nonlinear sources and number of connections on the PIM behaviors, followed by some experimental validation. The measurement results agree well with the theoretical calculations and circuit simulations, having a mean difference within 0.5 dB.
