MCX (micro coaxial connector) are coaxial RF connectors developed in the 1980s. They have the same inner contact and insulator dimensions as the SMB connector but are 30% smaller. MCX is standardized in European CECC 22220.[1]

Connector design[edit]

MCX connectors use a snap-on interface and usually have a 50 Ω impedance (some are 75 Ω) . They offer broadband capability from DC to 6 GHz.[2] The contact surfaces are gold-plated.

The outer diameter of the plug is approx 3.6 mm or 0.140 inch.

Use[edit]

MCX and the smaller MMCX connector are frequently used to connect external antennas to GPS receivers. They are also common on USB DVB-T tuners for computers and laptops, to connect an external antenna to the tuner.
