Currently,printed circuit boards are widely used in modern electronic devices.The increase in communication frequency,power,and data signal capacity has placed extremely strict requirements on the passive intermodulation performance of devices based on printed circuit boards.Therefore,this article comprehensively discusses the current research status of passive intermodulation on printed circuit boards at home and abroad.Starting from the relevant research on passive intermodulation mechanisms involved in circuit boards,it combs out the classic modeling of the current research on passive intermodulation mechanisms in printed circuit boards,and further summarizes the current hot research directions of passive intermodulation testing on printed circuit boards.This article summarizes passive intermodulation suppression methods from the selection of printed circuit board materials and planar circuit design.It will provide technical references for the study of passive intermodulation mechanisms in future engineering applications and the establishment of nonlinear models for passive intermodulation analysis.At the same time,it has important reference value in establishing a high-precision passive intermodulation testing platform,conducting research on passive intermodulation positioning and diagnosis technology,and establishing a passive intermodulation prediction and verification platform.
