　　RF connectors are mainly divided into RF coaxial connector, RF tri coaxial connector and dual core symmetrical RF connector. The main uses are as follows:

　　1. RF coaxial connector: mainly used to transmit transverse electromagnetic wave (TEM wave);

　　2. RF triaxial connector: it is mainly used to transmit transverse electromagnetic wave (TEM wave) or pulse wave when shielding efficiency is higher;

　　3. Dual core symmetrical RF connector: mainly used to transmit digital signals with low speed.

　　1) The main performance parameters of RF coaxial connector include characteristic impedance, service frequency, return loss, insertion loss, isolation, RF leakage, phase consistency, third-order intermodulation, etc.

　　2) Common materials and coating of RF coaxial connector

　　RF connector is mainly composed of outer conductor, inner conductor, insulating support medium and other parts, and its common materials are as follows:

　　Outer conductor: stainless steel passivation, copper alloy gold plating, copper alloy nickel plating, copper alloy ternary alloy plating, etc;

　　Inner conductor: gold plating on copper alloy, silver plating on copper alloy, etc;

　　Insulation support media: PTFE, Pei, LCP, etc.
