CC Series: Alternative Semi-Rigid & Semi-Flexible - Flexible Stable Phase Coaxial Cable
CC Series: Alternative Semi-Rigid & Semi-Flexible - Flexible Stable Phase Coaxial Cable offers excellent phase stability with improved flexibility compared to traditional semi-rigid cables. Designed for precision RF assemblies and microwave modules, this stable phase coaxial cable is widely used in radar electronics, satellite communication systems, RF test equipment, antenna measurement platforms and microwave signal routing applications.
CC Series: Alternative Semi-Rigid & Semi-Flexible Coaxial Cables
AO Microwave’s CC Series coaxial cables are designed to replace hand-formable (semi-flexible) and solid semi-rigid cables, combining standard flexible cable routing with the high shielding performance of a solid metal tube up to 40 GHz. Built with a solid or low-density PTFE dielectric core, these cables incorporate a silver-plated copper foil tape inner shield, overlaid with a high-density silver-plated copper wire outer braid and an FEP jacket. Operating across standard bands, our CC Series assemblies achieve an exceptional shielding effectiveness of typically > 100 dB, low VSWR, and stable phase performance under installation bends.
These highly shielded, flexible assemblies are engineered to eliminate the "spring-back" mechanical forces of hand-formable cables. They are critical for high-density cabinet routing, internal module connections in active transceivers, and automated test fixtures.
Eliminating Spring-Back Forces & High-Shielding Foil Technology
Solid copper-tube semi-rigid cables offer high shielding effectiveness (>110 dB), but are difficult to route, requiring dedicated bending tools. Hand-formable (semi-flexible) cables utilize a tin-filled wire braid; while easier to bend, they exhibit "spring-back" forces that put mechanical load on delicate solder joints and can gap over time, causing RF leakage.
AO Microwave resolves these mechanical routing issues by using silver-plated copper tape and foil shielding. By helically wrapping a highly conductive flat copper tape over the dielectric, we achieve 100% physical coverage. This tape shield is covered by a high-density copper wire outer braid, achieving a shielding effectiveness of > 100 dB (comparable to solid semi-rigid) while remaining highly flexible and eliminating spring-back forces.
Target Applications & Operational Advantages
By providing high shielding and flexible, spring-back-free routing, our CC Series cables secure critical RF connections:
Active Transceiver Module Connections
