Advanced Technical Materials (ATM) manufactures high performance microwave 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. This product line has five different sizes of cable designed to operate from DC-60 GHz. Please call us and discuss your needs with one of our design engineers.

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 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 cable form, or as fully guaranteed cable assemblies. ATM tests all cable and assemblies 100% for Impedance, Insertion Loss and VSWR, other electrical requirements can be tested for in our well equipped Test Lab. ATM works for our customers to provide great service, excellent pricing and fast deliveries, with the highest possible quality available in the microwave cable industry. Give ATM your toughest interconnection requirements and let us show you how we can help you save money and solve your interconnect problems.
