Johnson/Cinch Connectivity


SMPM Coaxial RF Connectors
Designed for HF Applications Where Spacing is Critical

Johnson / Cinch Connectivity offers the Johnson line of SMPM Coaxial RF Connectors. Distinguished for their size (about 35% smaller than the SMP design), the multi-functional high frequency push-on connector is suitable for use in a variety of applications. The sub-miniature, push-on style micro interfaces are becoming increasingly popular for the two-fold design benefit of allowing for a higher-density of connection points and maintaining solid Return Loss performance from DC-level frequencies up to 65GHz. The Johnson line of SMPM connectors are manufactured with high quality beryllium copper and brass components and designed to meet MIL-PRF-39012 and MIL-PRF-39012 specifications.
