The main working characteristics of RF connectors

RF connectors are electrical connectors that are generally used with coaxial cables. The advantage of RF connectors is better shielding effectiveness. The following are the working characteristics of RF connectors: 1. Impedance: Almost all RF connectors and cables are standardized with 50ohm impedance. The exception is the 75ohm connector for cable TV systems. RF coaxial cable connectors have to match the characteristic impedance of the cable is also important. Frequency range: RF connectors work in the frequency range in the field of high frequency and high speed must be concerned. Frequency is divided into several classes, such as 1 ~ 6GHz, or 0 ~ 18GHz, 20GHz, 27GHz, 40GHz, 50GHz, 67GHz, 110GHz or even higher. Insertion Loss: Loss is an indicator that all connectors are concerned about. Just usually RF connector loss will be relatively small (if too large, indicating a problem). Generally in the frequency range of concern are within 0.1 ~ 0.5dB. 2. Return Loss: In some of the engineers do digital circuits, VSWR is not so intuitive, so some will use the return loss to characterize. Use (plugging) times: for electronic engineers (RF engineers, SI engineers) may not be too concerned about the number of times the connector is used. The use of the number of times is generally considered to be the number of times after the insertion and removal of the connector performance has changed. General RF connector plugging and unplugging times is 500 or 1000 times, there will be higher requirements. If you want to do some experiments for this, we must be in a specific torque / torque, otherwise it is difficult to ensure that the number of times the requirements. Usually use the connector rarely reached this number of times, it is estimated that can be used 100 times or 200 times, the internal core has been deformed, because there is always the possibility of inserting a crooked or too much force and twisting.
