When signal integrity, shielding, and mechanical stability are vital, HUBER+SUHNER semi-rigid cable assemblies deliver seamless connectivity. We engineer these assemblies for environments where performance cannot be compromised, such as test and measurement, aerospace and defense, medical diagnostic devices and next-gen communications. 


HUBER+SUHNER semi-rigid cable assemblies offer unmatched precision, durability, and electromagnetic shielding. Designed to complement our flexible microwave portfolio, these semi-rigid solutions can be pre-bent to the exact specifications of our customers, using advanced CNC, automatic bending tools and manual bending techniques. 


This delivers consistent routing, compact form factors, and reliable performance across a wide range of demanding applications, including compliance to standard MIL-DTL-17.

Key features

  • Frequency range up to 67 GHz (cable assembly): Supports high-frequency applications with minimal signal loss
  • Pre-bent to customer specifications: Enables efficient, time-saving installations maximizing electrical performance
  • High screening effectiveness: Up to 120 dB @ 18 GHz for superior EMI suppression (depending on the selected connectors)
  • Multiple cable diameters available: From 0.020″ to 0.250″ to meet diverse electrical and mechanical needs
  • Wide operating temperature range: Reliable connectivity from -55°C to +125°C (up to +300°C available for selected sizes)
  • Wide range of RF/microwave connectors: Compatible with MCX, MMCX, MMPX, N, PC 1.0, PC 1.85, PC 3.5, QMA, SK, SMA, TNC and others to suit any applications.
