The third order passive intermodulation analysis of cable connector in mobile communication systems

Abstract

The relation of PIM power versus input power is presented, and the third order PIM product is predicted. The agreeable PIM power versus input power curve is obtained by regulating the polynomial coefficients. Comparing fitting results with the measured data for cable connectors in mobile communication systems, we verify the correctness and feasibility of the proposed scheme. Moreover, the time dependency of PIM sources is discussed ..
