MCX connector is a push in connection structure, with a compact appearance and convenient and fast connection of RF coaxial connectors. The characteristic impedance of MCX connectors is two resistance values: 50 Ω and 75 Ω. Due to the use of a push in connection method in MCX connectors, the connection and disconnection of the connectors are very fast, shortening the installation time of the connectors. MCX connectors still have good electrical performance when the frequency reaches 6GHz, and can be adapted to various cables including semi-rigid cables and flexible cables, with reliable connection and long service life.
