Semi Rigid Coaxial Cables

High-Performance Semi-Rigid Coaxial Cables

Mechanc manufactures 50 Ω semi-rigid coaxial cables for high-frequency systems where signal integrity, shielding, and precise mechanical routing are critical. Built around a solid metallic outer conductor, these cables deliver a combination of low RF loss, excellent electromagnetic shielding, stable impedance, and robust mechanical performance.

Unlike conventional flexible cables, a semi-rigid coaxial cable can be formed into a defined routing geometry and will retain that shape after installation. This characteristic makes it particularly valuable inside compact RF equipment, microwave modules, and other assemblies where cable position must remain controlled and repeatable.

Engineered for Stable High-Frequency Transmission

The solid outer conductor is a defining feature of semi-rigid RF cable construction. In addition to providing mechanical rigidity, it creates a highly effective RF shield and supports predictable electrical characteristics at microwave frequencies.

Mechanc offers semi-rigid cable solutions in different diameters and configurations, allowing designers to optimize their selection according to frequency range, attenuation, available installation space, power requirements, thermal conditions, and required bend geometry.

Smaller-diameter cables are particularly useful for densely packed RF layouts and miniature microwave assemblies, while larger constructions can be selected when lower attenuation or greater power capability is required.

Precise Routing for Compact RF Designs

Semi-rigid coaxial cables are widely used when an RF transmission line must follow a predetermined path within a device or system. The cable can be carefully formed around components and mechanical structures, then remain securely in its installed position without additional flexibility.

This makes semi-rigid coax an excellent solution for microwave circuits, RF modules, radar equipment, antenna feeds, laboratory instrumentation, telecommunications hardware, aerospace systems, defense electronics, and high-frequency test equipment.

The combination of compact dimensions, strong shielding, and controlled routing also makes semi-rigid cable particularly suitable for environments where RF components are positioned close together and electromagnetic interference must be minimized.

Semi-Rigid RF Cable Selection

Selecting the appropriate semi-rigid coaxial cable involves more than choosing a cable diameter. Engineers should consider the required maximum operating frequency, attenuation, impedance, power handling, minimum bend radius, operating temperature, outer conductor material, and overall cable dimensions.

Mechanc’s semi-rigid coaxial cable portfolio provides multiple options for different RF and microwave design requirements, from miniature interconnections in space-limited assemblies to low-loss transmission paths for demanding high-frequency systems.
