Optimal design of millimeter wave coaxial 1.85mm connector

Aiming at the inappropriate ways in the use of millimeter-wave coaxial 1.85mm connector, a model is established through simulation for simulation, and the optimized results are obtained. Use 3D high frequency simulation software (HFSS) to find out the general law between coaxial 1.85mm connector performance and air matching cavity parameters, avoid unnecessary troubles caused by port mismatch in high frequency circuit design and assembly, and analyze the millimeter wave coaxial 1.85mm connector offer a proven approach.

In recent years, my country's international situation has been severe, and national security has become increasingly prominent. The key millimeter wave coaxial 1.85mm connectors are important strategic materials for the national weapon equipment system, and the millimeter wave coaxial 1.85mm connector is developed and produced in aerospace, aviation, weapons, military ships, electronic countermeasures systems and other integrated circuits to transmit radio frequency. Electronic components indispensable for signal and energy. Its development and application are an important manifestation of the miniaturization and lightweight requirements of the whole machine. The replacement of the waveguide system greatly reduces the volume of the high-frequency interconnection system of the whole machine, and the disassembly complexity is greatly reduced. At present, it is mainly used to solve 30 Connection problems for high frequency transmissions at ~110 GHz, where large return loss, small insertion loss, and low VSWR can be obtained.

In engineering applications, there will be the following phenomenon: coaxial 1.85mm connector with good indicators is selected as the signal transmission port, but the indicators obtained in the actual test are poor. When troubleshooting, RF engineers tend to ignore the important link of connector port mismatch, because coaxial 1.85mm connectors are different from low-frequency SMA connectors, and their structure and assembly methods have strict requirements.
