Semi-Rigid FAQ

What defines a semi-rigid coaxial cable?
An RF interconnect utilizing a continuous solid metal outer conductor. It permanently holds its formed shape and provides exceptional 165 dB shielding.
How do standard, low-loss, and phase-stable models differ?
Standard offers broad routing economy. Low-loss minimizes attenuation via low-density dielectrics. Phase-stable maintains repeatable electrical lengths across temperature shifts.
What is the difference between operating and cutoff frequency?
Operating frequency is the recommended bandwidth for standard performance. Cutoff frequency is the absolute physical limit of the dielectric structure before higher-order modes propagate.
Are there strict bend radius constraints?
Yes. Bending tighter than the specified minimum static bend radius will permanently deform the dielectric and alter system impedance.
What is required to quote a custom formed assembly?
Please provide a 3D STEP file or a 2D drawing detailing coordinate points and bend radii, alongside your target frequency and connector interfaces.
