K-Flex Coaxial RF Cable
compare to Tflex®, M-Flex®, Storm Flex®, PhaseTrack® w/ TF4

Koaxis has developed our own line of flexible semi-rigid replacement cables, called K-Flex™, in order to control our sources of supply and to provide tighter tolerances vs similar cables available from several other sources. The result is industry-leading delivery and performance.
All K-Flex™ cables offer outstanding shielding for improved isolation and are a superior choice for smaller diameter RF cable applications, in which fleixbility and/or high-frequency operation are required. K-Flex™ cable is available in .047", .086, and .141" dia cables with a solid PTFE dielectric having a 70% Velocity of Propagation.
Low-loss variants of K-Flex™ are available in .120" dia with a Velocity of Propgation of 77%. K-Flex™ 120 has excellent Phase-tracking v Temperature, DC-40 GHz operation, and is an outstanding choice for Phased-array applications.
Koaxis also offers low-loss and Phase-stable v temperature variants in .047" and .086" dia cables with a Foamed PFA dielectric (a PTFE cousin), 78% Velocity of Propagation, and revolutionary Phase-stability v temperature delivering not only lesser overall Phase-change across its operating temperature, but virtually eliminating the dreaded "Teflon Knee".
