MCX :: Miniature Connector series

Friday, February 13th, 2009

Developed in the 1980s, MCX connectors are coaxial RF connectors that have the same inner contact and insulator dimensions as the SMB connector but are 30% smaller. They use a snap-on interface and usually have a 50 Ω impedance. They offer broadband capability from DC to 6 GHz.

While maintaining high performance, the reduced connector size benefits any applications where the space reduction matters such as GPS, Wireless communication, PCB layouts.
