COAXIAL CONNECTORS
OSI's Microwave Test Coaxial Adapters are precision-engineered for optimal microwave testing. Bridging different connector types, they guarantee seamless signal transmission in demanding environments.

Coaxial Connectors & Adapters
OSI's microwave test adapters provide reliable interconnection solutions for test system configuration and measurement standardization across DC~110GHz. Precision-machined for low VSWR and minimal signal degradation, our adapter portfolio supports a wide range of connector types—including 1.85mm, 2.4mm, 2.92mm, 3.5mm, SMA, and N-Type—enabling flexible test setup configuration and connector interface compatibility. Ideal for VNA calibration, test equipment integration, and cable assembly protection in laboratory and production environments.
Key Applications
Test System Integration
Configure and standardize connector interfaces across multi-vendor test equipment. Adapters enable seamless integration of instruments, fixtures, and cable assemblies with different connector types, reducing setup complexity and ensuring measurement consistency.
Connector Protection & Extension
Protect high-value cable assemblies and instrument ports from wear and mechanical stress. Adapters serve as sacrificial interfaces during frequent connection cycles, extending the operational lifetime of precision test cables and expensive equipment connectors.
Gender Adaption
Convert male-to-male or female-to-female connections in test configurations. Gender changers provide routing flexibility without requiring custom cable assemblies, simplifying inventory management and reducing lead times.
VNA Calibration & Measurement
Standardization
Enable calibration kit compatibility and measurement reference plane adjustments. Precision adapters support accurate de-embedding and error correction in vector network analyzer measurements, maintaining calibration integrity across frequency ranges.
