0.086'' Semi-Rigid Coaxial Cable 75 Ohm RF Feeder Cable for Aerospace and Defense

SR-086-75 is a 0.086 inch semi-rigid coaxial cable with 75 Ohm impedance designed for RF and microwave systems that require controlled impedance, compact routing, and stable signal transmission. Built with a silver-plated copper-clad steel center conductor, PTFE dielectric, and seamless copper tube outer conductor, this RF feeder cable provides low loss, strong shielding, and reliable performance across a wide frequency range. The semi-rigid copper shielding can be precisely formed during installation, allowing consistent routing inside RF modules, laboratory instruments, and microwave assemblies. With excellent shielding effectiveness, high power capability, and stable electrical characteristics, SR-086-75 is widely used in RF test equipment, signal distribution networks, high-frequency instrumentation, and specialized electronic systems requiring 75 Ω transmission lines.

A: SR-086-75 is typically used in RF and microwave systems that require 75 Ohm impedance transmission, including signal distribution circuits, measurement equipment, instrumentation, and specialized RF electronics.

A: The primary difference is the characteristic impedance. Standard SR-086 cables are usually 50 Ohms, while SR-086-75 provides 75 Ohm impedance, which is required in certain signal transmission, instrumentation, and impedance-matched RF circuits.

A: Yes. SR-086-75 follows the same 0.086 inch semi-rigid cable size, making it mechanically compatible with many UT-085-style cable routing spaces and connector tooling.

A: Typical SR-086 style semi-rigid cables can operate up to 40 GHz or higher, with some variants rated up to around 60 GHz depending on the specific design and application requirements.

A: Yes. Semi-rigid coax cables are designed to be formed into precise shapes using bending tools or fixtures. Maintaining the recommended minimum bend radius helps preserve impedance and electrical performance.

A: Common connectors for 0.086 inch semi-rigid coax include SMA, 3.5 mm, and other microwave connectors, depending on the required frequency range and application.

A: Yes. Due to its solid center conductor and copper tube outer conductor, the cable can handle relatively high RF power levels compared with many miniature flexible coax cables.

A: Yes. The cable can be provided as cut-to-length or pre-formed assemblies, allowing engineers to integrate it directly into RF modules, test systems, or production equipment.

A: The cable is designed for operation between −55°C and +125°C, making it suitable for industrial, aerospace, and laboratory environments.

A: Yes. SR-086-75 uses RoHS compliant materials, supporting global environmental and regulatory requirements.
