SMA Connector Dimensions

SMA connectors feature screw-type coupling. Semi-Rigid cabling extends their frequency range to 18GHz. SMA connectors offer broadband performance with low reflections and constant 50 ohm impedance. These properties, along with their minimum attenuation and low VSWR, have made the SMA connector extremely popular in the microwave community. LTI’s SMA connectors are designed to conform to MIL-C-39012 specifications.

N Connector Dimensions

N series RF connectors are 50 ohm constant impedance connectors with a consistently low VSWR across their frequency range of DC to 11GHz. They are high-quality medium sized connectors that are generally used with coaxial cables from .350" to .450" OD, but designs can also accommodate .078" to .875" cables. N type connectors are threaded and gasketed for weatherproof operation.

The threaded coupling incurs low noise and withstands shock and vibration. LTI’s N connectors are designed to conform to MIL-C-39012 specifications. Lighthorse Technologies offers a few 75 ohm impedance versions of N connectors. However; they are not mateable with the 50 ohm connectors.

SMB Connector Dimensions

SMB RF connectors are semi-precision subminiature devices that provide repeatable electrical performance from DC to 4 GHz. The SMB family of connectors provides a means of quick connect and disconnect through a snap-on type coupling, making them useful in areas that are inaccessible to normal mating action.

Its smaller physical size and snap-on coupling make the SMB an ideal general purpose connector where packaging density, ease of mating/unmating, and economy are prerequisites. Typical applications for SMB connectors are telecommunications, test equipment, instrumentation, and GPS. They are best suited for use with cables in the range of .070" to .120" in diameter, such as RG 178, RG 174, RG 316. The series is similar in size to the SMC connector but is generally used at a lower frequency. LTI’s SMB type connectors are designed to conform to MIL-C-39012 specifications.

SSMB Connector Dimensions

SSMB RF connectors are microminiature devices that provide repeatable electrical performance from DC to 3GHz. The standard mating design for SSMB series connectors is similar to that of SMB and SMC connectors but with the size reduced by approximately one-third. This makes them ideal for use in confined areas where the use of wrenches is not practical. They are lightweight, easy to connect and disconnect, vibration-proof, and highly reliable.

They are best suited for use with cables in the range of .070" to .120" diameters, such as RG-178, RG-174, and RG-316. Because of their small-size and tight tolerance, finishes other than gold plating are not recommended. SSMB type connectors have gained wide acceptance and usage in military radio systems, where small size is needed for miniaturization but ruggedness and reliability are very important.

The FAKRA: ISO 20860-1/DIN72594-1 and USCAR: SAE 2, 17, 18 standards designate several essential characteristics of FAKRA/USCAR connectors, including: RF electrical performance identical to an SMB coaxial connector, a plastic housing featuring mechanical and color coding (each color referring to a specific application), and high mechanical performance that meets the requirements of the automotive industry. Both FAKRA and USCAR compliant connectors are based on the coaxial SMB interface and are fully intermateable.

7/16 Connector Dimensions

7/16 series RF connectors are 50 ohm constant impedance connectors with repeatable electrical performance from DC to 7.5 GHz. They are medium-size rugged connectors and feature good power-handling capability. 7/16 connectors are designed to minimize signal distortion from intermodulation. Because of this, the standard plating is silver. Optional nickel plating should only be specified when low intermodulation is not a concern in your system design. At this time, Lighthorse Technologies only offers panel mount versions of the 7/16 as standard connectors. However, if you require a different mounting style, we will be happy to consider your requirements to provide a working solution.
