Overview
ORVEX RF coaxial adapters cover frequencies from DC to 110 GHz, offering a complete range of interface types and configurations, including SMA, N, 2.92 mm (K), 1.0 mm, and 7/16 DIN connectors.
Designed for demanding RF and microwave applications, precision models feature VSWR as low as 1.05:1, while high-power versions can handle kilowatt-level power transmission. Low-PIM models achieve intermodulation performance of ≤ -160 dBc, making them ideal for modern wireless communication systems.
Built for long-term reliability, our adapters operate in harsh environments from -65°C to +165°C and provide over 5,000 mating cycles. They are widely used in laboratories, wireless infrastructure, aerospace, defense, test & measurement, and satellite communication systems.
