Why RF connectors are becoming more and more popular

At present, with the continuous development of modern electronic countermeasure technology and military equipment, the detection ability of passive detection system to aircraft and its active electronic equipment has been significantly improved,RF ConnectorSurvivability and penetration capability in the modern combat environment are seriously threatened. So, what are the reasons for the popularity of RF connector design?

1. Structural stability

The insulator is received in the conductive housing, the interface end of the insulator has a dart-shaped lead-in tip that extends outside of one of the one end and the two ends of the housing, and a retaining sleeve is disposed around the conductive housing, the retaining sleeve having an engagement member for engaging with the insulator. A protective sleeve is used on the outside of the adapter to protect the internal components and improve the overall structural stability.

2, better performance

The locking mechanism of the radio frequency connector includes an unlocking member and a locking member. One end of the locking member is provided with an elastic arm along the axial direction, the inner circumferential surface of the other end is provided with a guide part, the guide part is provided with a guide groove along the axial direction, and the end of the elastic arm is provided with an elastic barb. The outer circumferential surface of one end of the unlocking member is provided with an unlocking barb corresponding to the elastic barb, the locking member is sleeved on the outer periphery of the unlocking member, the guide arm is inserted into the guide groove and can slide along the guide groove, and the locking mechanism is installed in the male end.

3. Advanced Materials

The millimeter wave RF connector contact mainly refers to the inner conductor, which includes pins and jacks. In order to make the product have higher reliability requirements, beryllium bronze should generally be selected as the material of the contact. Beryllium bronze contact under high stress can not yield deformation or fracture, maintain a long-term high stress state without relaxation, can provide a large force in a limited space, and has high electrical conductivity and thermal conductivity, excellent corrosion resistance and good process performance.

The RF connector analyzes the influence of stub, pad, anti-pad, inner pin diameter and other factors on the transmission performance of PCB interface. The theoretical values of key parameters such as insertion loss, return loss, voltage standing wave ratio and characteristic impedance under different boundary size conditions are obtained by simulation calculation, and it is believed that the application will be more and more widely in the future.
