SMA Series Connectors
SMA Connectors are high-performance subminiature connectors suitable for use at up to microwave frequencies. SMA specific coupling technology minimizes reflections and attenuation at higher frequencies while providing significant mechanical durability and strength. SMA connectors are available in brass, beryllium copper and stainless steel constructions. These semi-precision, 3mm, high frequency connectors give repeatable electrical performance from DC to 18 gigahertz. Moderately priced, they are also ideal for use in general purpose applications at lower frequencies, where size and cost are critical considerations.
