MCX Series

MCX miniature connectors are based on the CECC 22220 standard. They are designed for 50 Ohm systems with working frequency up to 6GHz.
The snap-on mating design offers the user smaller size compared to SMB series (30% space reduction). MCX connectors are suitable where space, and weight performance are required.
The major application of MCX series connectors are GPS, wireless communication & test devices.
