Johnson-Cinch Connectivity Solutions 1450901811 RF Connector

The SMK 50 Ohm Connectors (2.92mm) are precision, gold-plated semi-rigid coaxial adapters designed for high-frequency applications up to 40 GHz. Manufactured with stainless steel bodies and beryllium copper contacts, these connectors ensure excellent electrical performance with VSWR less than 0.20 at 40 GHz. They feature a hermetic seal, field replaceability, and robust MIL-STD-348 compliance. Suitable for microwave, RF, and military applications, they offer high durability, thermal stability from -65°C to +165°C, and low insertion loss for reliable signal transmission. Installation involves careful microstrip transition adjustments for optimal impedance matching.
