Amphenol RF ATC-PS Phase Stable Test Cables

Amphenol RF ATC-PS Phase Stable Test Cables are amplitude/phase stable low loss test cables and are a full Amphenol solution. These pre-configured SMA and N-Type assemblies feature precision machined stainless steel connectors terminated to triple shielded, ultra-low loss cables manufactured by Times Microwave Systems, a division of Amphenol. The ATC-PS test cables are ideal for test and measurement applications up to 20GHz. These SMA and N-Type cable assemblies feature robust strain relief construction to ensure the stability of the center contact relative to the connector body. This rigidity allows for optimal performance and consistent phase stability.
