SMA Female to mmcx for RG178

RF connecting cable is a kind of cable mainly used for connecting RF energy devices with electrical and mechanical properties. RF connection cable consists of inner and outer conductors and dielectric. The inner conductor is usually made of copper, which is required to be free of impurities, indicating clean, smooth and sleek, and the diameter should be stable and with small tolerances. The outer conductor has two basic roles: the first is to act as a circuit conductor, and the second plays a shielding role. The choice of material for the insulation medium of the RF connection cable and its structure are very important, all important properties such as attenuation, impedance and return loss are very much related to the insulation medium.

The working principle of RF connecting cable is mainly to transmit RF energy through electromagnetic induction between inner and outer conductors. When the RF signal passes through the inner conductor, the stability and reliability of the signal transmission is ensured because the diameter of the inner conductor is stable and has a small tolerance. At the same time, due to the shielding effect of the outer conductor, the leakage of RF signals and interference can be effectively prevented, improving the quality and stability of signal transmission.

Requirements for the selection of RF Connection Cables include characteristic impedance, rated power, attenuation and maximum operating voltage. In the use of RF connection cable, need to pay attention to matching the same characteristic impedance of the cable plug, cable socket and coaxial transfer switch, can not be mixed. RF connecting cables are used in a wide range of applications, including wireless communications, broadcast data transmission, public antennas, closed-circuit television monitoring systems.
