Engineering FAQ
What is a General Purpose flexible RF cable?
+
It is a standard 50 ohm coaxial platform designed for everyday RF interconnects where balanced performance and routing flexibility are the primary requirements.
When should I choose General Purpose instead of Low Loss?
+
Use this platform for standard routing where balanced performance is sufficient. Move to Low Loss cable when attenuation becomes the primary concern.
Which model is recommended for subsystem links?
+
The I26 and I40 models are the primary choices for subsystem links, offering frequency coverage up to 26.5 GHz.
Are terminated assemblies supported?
+
Yes. Vinstronics provides custom assemblies with defined lengths and connector interfaces based on these mainline platforms.
