Johnson product line of Emerson Connectivity Solutions designs and manufactures an industry leading line of RF coaxial connectors and adapters, which are available in both 50 and 75 ohm versions. Johnson connectors are designed to provide the highest quality data transmission for audio, video and data applications. The Johnson line of products can address frequency ranges from DC to 46GHz and all sizes from Ultra-miniature interfaces (UMC), Micro-miniature, (MCX, MMCX, SMP), Subminiature (SMA, SMB, SMK, kwiQMAte ™), Medium connectors (Type N connectors) through to large connectors (DIN7/16). The breadth of products available within the Johnson range includes board and cable mount connectors as well as semi-rigid, conformable, and flexible RF coaxial cables.
Emerson Network Power Connectivity Solutions offers the Johnson line of SMPM 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.
Johnson / Emerson Connectivity Solutions offers a wide range of 50Ω and 75Ω Fixed Length RF Cable Assemblies from 3" to 60" in series BNC, MCX, MMCX, N, SMA, SMB, and UMC. Johnson's Fixed Length RF Cable Assemblies are available in many cable, plug, and jack types (straight, right angle, bulkhead, mini), as well as hand formable types. Johnson's line of RF Coax Cable Assemblies can meet the most unique specifications.
Johnson / Emerson Connectivity Solutions offers SMA Fixed Commercial Attenuators in a rugged stainless steel body and are available in 1, 2, 3, 6, and 10 db. These non-inductive resistors satisfy almost any requirement involving a reduction in power levels under 2W. The SMA Fixed Commercial Attenuators help reduce impedance mismatches in high frequency circuit systems and improve impedance matches between amplifiers and filters.
Johnson / Emerson Connectivity Solutions SMP blind-mate connector aids in high-density packaging design, as well as axial and radial misalignment issues. The SMP interface offers superior performance up to 40GHz and is compatible with all SMP and GPO® connectors. The blind-mate connector offers high electrical reliability where extreme shock and vibration conditions are experienced.
Johnson / Emerson Connectivity Solutions SMA Hand Formable Cable Assembly is a fixed-length cable assembly and
an excellent alternative to semi-rigid cables, which are more costly
and less flexible during early design stages. Ideal for RF/Microwave
applications, this SMA cable effectively eliminates additional
tooling charges. When RF interference is not an option, these cables
provide 100% shielded cable coverage assuring an outstanding VSWR and
low insertion loss of up to 18GHz.
