How to choose RF connectors when using them

1.  Actual frequency range of use: The selected RF connector should conform to the actual frequency range of use.2.  Electrical performance: Straight RF connectors have better electrical performance than curved connectors, with standing wave ratio and insertion loss being key indicators. Low standing wave ratio and good performance; Low insertion loss results in high signal transmission efficiency.3.  Impedance matching: The selected RF connector should have the same impedance as the connected RF connector or cable to ensure stable signal transmission.4.  Mechanical performance: The EMC performance of threaded connectors is better than that of slot and push-pull connectors, making them suitable for applications that require high electromagnetic compatibility.5.  Materials and coatings: When there are special environmental requirements, the materials and coatings of RF connectors need to be considered to ensure their stability and durability in specific environments.7.  Universal and high-performance requirements: If a universal RF connector can meet the requirements, then a high-performance RF connector is not chosen to reduce costs.

Working principle of RF coaxial connector

1. Electromagnetic field coupling transmissionThe inner conductor (center pin) and the outer conductor (outer sleeve) form a coaxial structure, and radio frequency signals propagate in the form of electromagnetic waves in the medium between the two. The electromagnetic field forms coupling between the outer surface of the inner conductor and the inner surface of the outer conductor, completing energy transfer.2.  TEM wave transmission modeThe main mode of coaxial transmission line is transverse electromagnetic wave (TEM mode), and the direction of electric and magnetic fields is perpendicular to the propagation direction, ensuring the stability of signal transmission. The characteristic of this mode is that electromagnetic waves have no longitudinal component, and the energy oscillates completely in the transverse plane, avoiding phase delay and signal distortion.3.  Shielding and impedance matchingThe outer conductor serves both shielding and grounding functions, effectively isolating external electromagnetic interference and preventing internal signal leakage through the conductive properties of its inner and outer surfaces. The symmetry and uniform distribution of the coaxial structure ensure the continuity of the characteristic impedance, reducing reflection and standing wave losses.
