Description

Technical Field

[0001] The utility model belongs to the field of antenna testing tools, and in particular relates to a base station antenna PIM testing knocking platform. Background Art

[0002] PIM refers to the mixing interference signals caused by the nonlinear characteristics of various passive components (such as antennas, cables or connectors) between two or more RF signals in the RF signal path. In high-power, multi-channel systems, ferromagnetic materials, dissimilar metal welding points, metal oxide contacts, contaminated components and loose RF connectors can all cause signal mixing, thus forming PIM interference signals.

[0003] Therefore, during the test process, it is usually necessary to use tapping to simulate the mechanical vibration or impact that the antenna may be subjected to in actual use, so as to detect whether the PIM characteristics of the antenna in this case meet the requirements.

[0004] The current knocking mechanisms are often complex in structure and have high cost of use, so there is a need for a simple, convenient and low-cost automatic knocking system. Utility Model Content
