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.
