2.92 mm Connectors

2.92 mm Connectors

Amphenol RF offers 2.92 mm connectors designed for precision laboratory use and SATCOM applications. This connector series is engineered to offer low VSWR and excellent return and insertion loss, along with high power handling capabilities. 2.92 connectors are sometimes referred to as K connectors and have the ability to mate with SMA, 3.5 mm and other K or 2.92 mm interconnects.

2.92 mm connectors utilize a smaller internal body diameter and unique air dielectric which allows it to operate up to 40 GHz. With a shorter male pin than both the SMA and 3.5 mm connector, the bodies of the male and female connectors engage before the pin and socket contacts. This feature mitigates wear from mating misalignment with dissimilar interfaces.
