Flexible RF Coaxial Cable
Flexible RF Coax Cable and Connectors
Advanced Technical Materials (ATM) manufactures high performance microwave coax RF cable that utilizes only the very best materials, incorporating proprietary manufacturing methods, which yield very low Insertion Loss characteristics, high power capability and is Amplitude and Phase Stable on a level not readily available in the microwave industry.
ATM RF Cables have five different sizes of coaxial cable designed to operate from DC-60 GHz. We can also manufacture custom RF cable assemblies as required. Please call us and discuss your custom RF cable requirements with one of our design engineers.
Superior Coax RF Cables
ATM utilizes a solid, silver plated copper center conductor and Expanded PTFE dielectric material which allows for very low Insertion Loss and high power handling capability.
The outer conductor is a flat, silver plated copper foil wrapped helically around the dielectric and mechanically locked to the dielectric core to promote superior phase and amplitude stability, as well as, very low VSWR performance.
A silver plated copper, braided shield is then added to increase the axial tensile quality of the cable and further enhance RF leakage characteristics. The RF cable outer jacket is a tough, high temperature thermoplastic that can withstand temperatures from -65° to +200° Celsius.
All this adds up to a very superior microwave cable product that can meet the most demanding requirements. ATM cables meet military specifications for MIL-C-17 and MIL-DTL-87104. ATM connectors meet MIL-C-39012. This product can be sold in bulk raw coaxial cable form, or as fully guaranteed RF coaxial cable assemblies.
High Quality RF Cable Assemblies
ATM tests all coaxial cable and coax cable assemblies 100% for Impedance, Insertion Loss and VSWR. Additional coax RF cable electrical requirements can be fully tested and examined in our well equipped Quality Control Test Lab.
Custom RF Cable Assemblies
ATM can create custom coaxial cable assemblies to your challenging specifications. Our design engineers stand ready to assist you with your next RF cabling project by working with you to produce coaxial cable assemblies that will exceed your expectations.
ATM works for our customers to provide great service, excellent pricing and fast deliveries, with the highest possible quality available in the microwave RF cable industry.
Give ATM your toughest interconnection requirements and let us show you how our custom RF cables can help you save money and solve your interconnect problems.
