CZ Series: Multicore Ultra Soft Low Loss Coaxial Cable
Facing tight routing in complex cabins or frequent cable wear in harsh fields? AO Microwave’s CZ Series offers ultra-soft, low-loss flexible coaxial cables up to 40 GHz. Featuring stranded silver-plated copper conductors and rugged PUR jackets, these cables eliminate installation stress on connectors and resist environmental cracking. They deliver 90 dB shielding effectiveness and stable transmit power, making them the ideal choice for compact module interconnects and rugged field tests.
Multicore Ultra Soft Low Loss Coaxial Cables for Complex Layouts
Are you struggling to route stiff high-frequency cables through tight spaces without stressing your delicate connector solder joints? Or concerned about cable cracking and signal drift in harsh, high-vibration field environments? AO Microwave’s CZ Series multicore ultra-soft coaxial cables are engineered to eliminate these exact integration challenges, offering exceptional flexibility and stable transmission up to 40 GHz.
By combining a highly supple physical structure with rugged environmental protection, the CZ Series brings tangible operational benefits to your systems:
- Stress-Free, High-Flexibility Routing: Built with a multi-strand silver-plated copper center conductor. This stranded configuration makes the cable ultra-soft and highly limp, allowing it to bend smoothly in tight spaces (static bend radius down to 18 mm) without pulling or shearing your connector joints.
- Uncompromised Outdoor & Field Lifespan: Protected by a rugged, weather-resistant Polyurethane (PUR) jacket. This FEP-alternative jacket does not stiffen or crack in sub-zero temperatures (operating from -40°C to +85°C) and resists abrasions, protecting your systems from environmental degradation.
- Stable Signal Transmission up to 40 GHz: Utilizes high-purity solid PTFE dielectrics to achieve a propagation velocity (Vp) of 76% with low VSWR, ensuring excellent high-frequency signal delivery across wide bands.
- Excellent Interference Containment: Features double silver-plated copper wire braids, providing a shielding effectiveness of > 90 dB to prevent cross-talk and maintain clean signal paths in tightly packed modules.

CZ Series Coaxial Cable Selection & Engineering Guidelines
When routing high-frequency coaxial lines into dynamic radar pedestals or narrow vehicle networks, managing space-limiting parameters and cable softness is essential:
Selecting the Right Jacket Outer Diameter
The outer diameter (Jacket OD) of the CZ Series ranges from 3.60 mm for CZ360 up to 8.00 mm for CZ800. For extremely tight spaces requiring high frequencies up to 40 GHz, the thin profile of CZ360 is ideal. For systems requiring higher continuous-wave power and lower loss, larger sizes like the 8.00 mm CZ800 provide excellent performance.
Adhering to Static vs. Dynamic Bending Limits
To prevent physical deformation of the dielectric layer under bending, you must adhere to our specified bending limits. For permanent, fixed layouts, the static bend radius must be respected (e.g., 18 mm for CZ360 up to 40 mm for CZ800). For dynamic, continuous-motion applications, use the dynamic bend limits (e.g., 36 mm for CZ360 and 80 mm for CZ800) to ensure a long mechanical lifespan.
Overcoming Critical Environmental & Physical Challenges
Active tracking systems and outdoor defense equipment face strict physical and environmental constraints. We optimize our CZ Series to resolve common integration bottlenecks:
Preventing Solder Joint Stress and Connector Shear
Standard solid-core cables are physically stiff, transferring bending stress directly to the connector's internal solder joints. During repeated movement or routing, this stress can shear the joint, causing physical failures. Our CZ Series resolves this by using an ultra-soft stranded silver-plated copper inner conductor. This multi-strand core absorbs mechanical flexing forces, preventing tension from pulling at your connector joints.
Withstanding Tough Field Environments
Outdoor coaxial runs are subjected to continuous solar radiation, humidity, and wide temperature swings. Standard jackets can crack under these conditions. AO Microwave's CZ Series is encased in highly rugged, UV-resistant Polyurethane (PUR) jackets. Operating reliably from -40°C to +85°C, PUR resists abrasion and weathering, protecting your hardware from expensive field downtime.
