This page will explain some cable and connector terminology and technologies. For those of you with cable questions, a good contact is Ruth Fawson, her company RF Connections sponsors our page on microwave connectors.

Industry standard coax cables

Below is a table the characteristics of many popular coaxial cables. RG cables refer to an ancient MIL spec, where RG refers to "radio guide". These are typically not used beyond a few GHz.

SR cables refer to semi-rigid.

D is the outer diameter of the dielectric, and d is the diameter of the center conductor.

One of these days we'll compile more cable data and offer it as an Excel download. Feel free to contribute!

Coax cable vendors

Sorry, we don't recommend coax cable vendors for free, Mr. Cable Vendor. You can put a banner ad here, if you show us the money! Why wouldn't you you want potential cable customers to see your name on this page hundreds of times per month? Contact Marketing@microwaves101.com. With your cable information, this page is set to take off.

Some specialty topics we hope to deal with soon:
