The Connex SMA connectors are semi-precision, sub-miniature, high-frequency connectors which offer reliable broadband performance DC to 18GHz with low reflection and constant 50 Ohm impedance. The main features are high mechanical strength, high durability and low VSWR. Matured design principles, careful manufacturing at all stages and a thorough quality assurance organization are the bases for the well-known quality of Connex SMA connectors. All connectors, unless otherwise noted, are Commercial Grade construction, gold plated brass bodies with 50µ gold contacts. All insulators are teflon. All other parameters are equal to Mil Standard construction.
