Enabling highly precise measurements with 2.92mm connectors

Amphenol RF has introduced the 2.92mm connector interface into its robust portfolio of RF interconnect options. This connector series delivers low VSWR, excellent return and insertion loss, and high-power handling capabilities. The connectors, sometimes referred to as K connectors, are able to mate with SMA, 3.5mm and other K or 2.92mm interconnects. With performance up to 40GHz, this connector series is excellent for varied applications, including test and measurement, defence, and microwave applications.

The connectors are comparable to the SMA interface but use a smaller internal body diameter and unique air dielectric, which enables them to function at a higher frequency range. With a shorter male pin than the SMA and 3.5mm connector, the bodies of the male and female connectors engage prior to the pin and socket contacts. This feature mitigates wear from mating misalignment with different interfaces.

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