Coax Cable & Connector Specifications
Advanced Technical Materials manufactures high performance coaxial microwave cable for the Satcom Ka-Band. Our cable covers the 18.3 - 31.0 GHz band which yields very low Insertion Loss characteristics, high power capability and is Amplitude and Phase Stable.
This specific coaxial cable line has two different sizes of cable, CF-210 for the downlink 18.3 - 20.2GHz and CF-135 for the uplink 27.5 - 31.0GHz and full Ka-Band 18.3 - 31.0GHz. Cable assemblies are available with SMA and 2.9smm connectors. Please call us and discuss your needs with one of our design engineers.
A) Silver Plated Copper Center Conductor
B) Expanded PTFE Dielectric Core
C) Silver Plated Copper Outer Conductor
D) Silver Plated Copper Outer Shield
E) FEP Outer Jacket, Black
