RF Cable by MegaPhase

Note : Your request will be directed to MegaPhase.

The Thermal VAC cables from MegaPhase are Thermal Vacuum Cables that operate from 0.3 to 50 GHz. These cables are manufactured specifically for users that need to test space or airborne systems and components. The cables have a shielding effectiveness of -110 dB and a VSWR of less than 1.50:1. They have a propagation velocity of 69%, a time delay of 1.47 ns/ft, and a capacitance of 95.1 pF/m.

These cables have an inner conductor of solid Ag-plated Cu and an outer conductor of GrooveTube Cu. They have a finished outer diameter of 0.285 inches and a static bend radius of 1.5 inches. These cables can be used to create coaxial cable assemblies with 1.85 mm, 2.4 mm, 2.92 mm, 3.5 mm, 7 mm, 7-16 DIN, BNC, SMA, Type N, TNC, ZMA, ZN connectors. These phase stable cables are ideal for high bay testing of RF payloads, and applications in thermal vacuum chambers, altitude chambers, thermal shock chambers, or any other application requiring thermal stability.
