Features and Benefits

Foam-Core Ultra-Low-Loss Coaxial Microwave Cable

Temp-Flex Foam-Core Low-Loss Flexible Microwave Cable combines space savings with an effective dielectric that eliminates “phase knee” and provides ease of termination. Customers will find that this rugged cable is able to withstand harsh environments at high frequencies while providing high performance.

Solid-Core Flexible Low-Loss Microwave Coaxial Cable

Temp-Flex Solid-Core Flexible Microwave Cable, with solid fluoropolymer (PFA, FEP) insulation delivers phase-stable performance at a range of temperatures while attaining competitive loss characteristics as compared with PTFE. The advantage of PFA and FEP is the elimination of the phase knee at room temperature. Therefore, the cable’s performance is more phase stable during temperature swings.

Foam- and solid-core versions

Both the foam- and solid-core versions offer standard sizes down to a 1.194mm shield OD, making them ideal for applications with rigid space limitations. The compactness of these microwave cables will help mitigate space constraints and facilitate design flexibility.

Overview

Medical, test and measurement, and aerospace and defense industries require cables that are reliable in harsh environments and are easy to terminate. Microwave cables with ePTFE insulation achieve minimal-loss characteristics, but these cables experience a phase-knee effect at room temperature, meaning environments with temperature swings can affect cable performance. Temp-Flex Solid- and Foam-Core Low-Loss Flexible Microwave Cable, with fluoropolymer insulation, deliver phase-stable performance at a range of temperatures while attaining competitive loss characteristics as compared with ePTFE.

Space-constrained applications, such as medical devices, as well as test and measurement, require cables that not only are stable in varying temperatures but also have small outer diameters. Both Solid- and Foam-Core versions offer sizes down to 1.194mm shield OD, making it ideal for applications with strict space limitations.

Frequently Asked Questions

What dielectric does the solid core use?
Temp-Flex Solid-Core Flexible Microwave Cable is unique compared to major competitors because it utilizes a solid Fluoropolymer (PFA/FEP) dielectric rather than a tape-wrapped PTFE ALL construction.

What is the advantage of this dielectric?
PFA/FEP eliminates the phase knee at room temperature, which means the cable’s performance is more phase stable during temperature swings.

What other advantages does solid-core offer?
Its high-temperature fluoropolymer dielectric is stable under flex.

What is the advantage of a foam-core microwave cable?
The extruded foam eliminates the phase knee at room temperature, which means the cable’s performance is more phase stable during temperature swings.

What other advantages does foam-core offer?
The high-temperature foam fluoropolymer withstands soldering temperatures for ease of termination to RF connectors.
