Amphenol RF introduced the 2.92mm connector interface in portfolio of RF interconnect options. This connector series is engineered to offer low VSWR and excellent return and insertion loss, along with high power handling capabilities. 2.92mm connectors, referred to as K connectors, can mate with SMA, 3.5mm and other K or 2.92mm interconnects. With performance up to 40 GHz, the connector series is ideal for test and measurement, military, and microwave applications.

2.92mm connectors are similar to the SMA interface but utilize a smaller internal body diameter and unique air dielectric which allows them to operate at a higher frequency range. With a shorter male pin than both the SMA and 3.5mm 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.

The ruggedized construction of the 2.92mm connector series is designed with the popular threaded coupling mechanism for secure and reliable mating. Both the jack and plug are manufactured with gold-plated, stainless-steel bodies and gold-plated, beryllium copper contacts. The connectors also meet MILSTD-348 standards and are most often used for optical testing, lab and bench testing, satellite communication equipment (SATCOM) and quantum computing.
