MCX connector
The MCX connector belongs to the miniaturized RF connectors. It dates back to the 80s and complies with the European specifications according to CECC 22220.
The dimensions of the inner conductor and PTFE dielectric are the same as those of the SMB connector, but the outer diameter is only 3.5 mm. The high-quality MCX connector is available with impedances of 50 ohms and 75 ohms. It can be used in the frequency range up to 6 GHz, has an insertion loss of 0.10 dB at 1 GHz and a snap lock.
The thin coaxial cables with a diameter of 2.5 mm can be connected to high-frequency cables. Examples: RG-174 and RG-188. MCX connectors are used on printed circuits, in instruments, WLANs, in antenna and RF amplifier technology. Ina scaled-down version, the MCX connector is called MMCX.
