Abstract

The embodiment of the invention provides a communication device which comprises a first metal piece and a second metal piece, a gap exists between the first metal piece and the second metal piece, the gap is coated with a conductive material, so that the conductive material can wrap the gap, electromagnetic waves cannot reach the gap, an intermodulation source is generated, and the PIM problem is solved. Moreover, the conductive material can be fixed at the discontinuous position of any two structural members in a dispensing manner, so that the PIM problem is systematically and comprehensively solved.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 202110622388.9 and the application name "Method for Solving PIM Based on Conductive Adhesive" submitted to the China Patent Office on June 3, 2021, the entire contents of which are incorporated in this application by reference . technical field [0002] The embodiments of the present application relate to the field of wireless communication technologies, and in particular, to a communication device. Background technique [0003] With the rapid development of modern mobile communications, the data and voice data required to pass within a fixed bandwidth are increasing. Since the transmission medium has certain nonlinear characteristics, two or more frequencies will be mixed together in nonlinear devices. A spurious signal is generated—passive intermodulation (PIM) problem. When the passive intermodulation falls within the receiving frequency band of the base station, the...
