Maximum Operating Frequency
The Micro CoaXial (MCX) is a miniature RF connector featuring snap-on coupling. The series is ideal for lightweight and space-limited applications, with has the same inner and outer contact interface dimensions as SMB but 30% smaller. The connector design has been standardised under European CECC 22220, and IEC 61169-36 specifications. Despite standards identifying an operating frequency to 3 GHz, most manufacturers commercially offer connectors to 6 GHz.
The connector was developed in the 1980s by Huber+Suhner, of which MCX is a trade name.
MCX connectors are widely used in GPS, modems, and Wi-Fi hardware due to their low cost and good broadband performance DC to 6 GHz, covering most RF applications.
Also available in a 75 Ω variant.
