“…According to the measurement results, the coefficients a 3 and a 5 can be obtained by solving a binary linear equation group [13]. With the determination of all the coefficients, as shown in Table 1, the theoretical nonlinear transfer functions of four types of connectors are completed.…”

Passive intermodulation (PIM) is usually expressed by the third‐order intermodulation power excited by two‐tone signal, which has limitations in characterising nonlinear distortion of signal in actual communication system. The effect of PIM on modulated signals are analysed at both the transmit and receive port with multiple passive nonlinear sources. Four types of coaxial connectors are adopted to represent four different levels of PIM. The equivalent circuits of PIM sources in series or parallel are proposed. With the circuit simulations and theoretical modelling, the effect of PIM on the analog and the digital modulation signals are analysed respectively. Two indexes of adjacent channel leakage ratio and error vector magnitude are modelled, showing the PIM effect at transmit port. A system model of a transmit‐receiver is provided, investigating the effect of PIM on the symbol error rate in a receiver. The effects of PIM distortion on different modulated signals are observed both in experimental measurements and simulation tests, verifying the theoretical models.

“…The model and characterisation of PIM has aroused the interest of researchers aiming to solve the PIM issues in RF devices. The generation mechanism of PIM often involves mechanics [3,4], heat [5][6][7], electromagnetic field [8][9][10], electrical contact [11][12][13][14][15] and so on.…”

A novel method for modelling the passive intermodulation (PIM) in radio frequency (RF) devices, which works as a complex non-linear system, was proposed. Both behaviour modelling and experimental validation were introduced to clarify the generation of PIM in a parallel and series non-linear system. Taking the coaxial connector as an example, two types of N-type connectors with 4 and 6 contact petals were selected and put into research. The measurements both agree well with the predicted results, validating the proposed model.
