CT Series: Economical Internal Interconnection Coaxial Cable
Tired of rigid cables straining your solder joints? AO Microwave’s CT Series offers economical, highly flexible internal interconnect cables up to 40 GHz. Designed to replace semi-rigid and semi-flexible lines, these FEP-jacketed cables eliminate spring-back forces and prevent joint shear. With solid PTFE dielectrics, 90 dB shielding, and outer diameters from 1.45mm (CT160) to 7.00mm (CT700), they ensure stable, low-loss routing for compact chassis and radars.
Economical Internal Interconnection Cables to Replace Semi-Rigid and Semi-Flexible Lines
Are you finding solid semi-rigid cables difficult to shape and route inside complex chassis, or struggling with "spring-back" forces in hand-formable cables that stress delicate PCB solder joints? AO Microwave’s CT Series internal interconnection coaxial cables are engineered as a highly flexible, low-loss, and cost-effective alternative to eliminate these structural routing challenges up to 40 GHz.
By combining high mechanical compliance with robust electrical shielding, the CT Series delivers direct integration advantages for your active modules:
- Eliminate Solder Joint Stress & Spring-Back: Designed as a flexible, form-conforming alternative to rigid copper-jacketed (semi-steel) and hand-formable cables. It routes smoothly without spring-back memory, preventing mechanical strain from shearing board-level connectors.
- Maximize Layout Density in Narrow Spaces: Features an exceptionally tight static bend radius (down to 7.5 mm for CT160). This allows you to construct neat, space-saving layouts inside compact active chassis, radars, and sub-systems.
- High-Frequency Low Loss & Low VSWR: Built with highly conductive silver-plated copper conductors and solid PTFE dielectrics. The CT280 (2.65 mm OD) supports operations up to 40 GHz, ensuring highly stable signal transmission.
- Durable FEP Protection over Wide Temperatures: Encased in premium Fluorinated Ethylene Propylene (FEP) jackets rated from -55°C to +125°C. This ensures consistent electrical parameters and prevents cable degradation under extreme operating conditions.
Review our physical parameters and attenuation tables below to find the exact CT Series outer diameter (ranging from 1.45 mm for the micro-scale CT160 to 7.00 mm for the low-loss CT700) optimized to simplify your next high-density layout.
The Physics of Flexible Routing & Strain Elimination
In high-density RF compartments, routing stiff semi-rigid cables can exert severe mechanical tension (spring-back) at the connection points. This tension is transferred directly to delicate PCB-mounted connectors, which can shear internal contacts and cause high reflections.
AO Microwave's CT Series resolves this problem by incorporating a highly compliant double-braided silver-plated copper wire outer shield. When bent, these flexible braids deform plastically to conform to your layout, absorbing mechanical stresses and eliminating the spring-back force entirely. This protects your board-level solder joints and secures long-term connection reliability.
Target Applications & Operational Advantages
By combining high mechanical compliance with low insertion loss, our CT Series internal interconnect cables secure critical RF signal paths:
Internal Chassis Connection
Function: Connects active MMIC devices, filters, and sub-assemblies inside dense equipment chassis.
Advantage: Exceptional mechanical flexibility and tight bend radiuses (static bend down to 7.5 mm) simplify cable routing in confined spaces, maintaining stable VSWR.
Phased Array Radar Routing
Function: Routes phase-matched signals inside multi-channel phased array radar systems.
Advantage: Low-profile design and double-braided shielding achieve a high shielding effectiveness of 90 dB to prevent cross-talk.
Replacement for Semi-Rigid Cables
Function: Replaces solid copper-jacketed cables on automated test fixtures and inside dense cabinets.
Advantage: Eliminates spring-back forces, preventing mechanical strain from pulling at your connector joints and reducing installation time.
