Bulgin 2.92mm Radio Frequency (RF) Connectors are subminiature connectors that are also known as K connectors, K-type, or SMK adapters. The series features a DC to 40GHz frequency range, 50Ω impedance, and >5000MΩ insulation resistance. Bulgin 2.92mm RF connectors are constructed with beryllium copper contacts, brass or stainless steel bodies, and male or female threads in plug or jack styles. These connectors have a thicker wall than standard SMA connectors and mate with SMA or 3.50mm connectors. Typical applications include high frequency and test and measurement.
