MCX microminature RF connectors are suitable for 50 ohm applications an provide repeatable performance from DC to 6GHz. The snap on coupling feature allows ease of assembly in dense packaging layouts. The design of the connector encompasses the need for size reduction, low weight, durability,and reliable perfomance. MCX type connectors enable a 30% space reduction over similar SMB/SMC types. LTI MCX connectors are designed to conform to CECC 22220 specifications.
Typical applications for MCX connectors include GPS, wireless communications and automotive.
