Molex featured its new Temp-Flex foam-core ultra-low-loss coaxial microwave cable in booth 1911 at the IEEE 2016 International Microwave Symposium (IMS) in San Francisco. Temp-Flex foam-core cable combines space saving with an effective dielectric that eliminates phase knee and provides ease of termination. It also achieves ?80 percent velocity of propagation (VOP) loss characteristics, which produces more reliable signal performance and lower loss characteristics than air-enhanced PTFE cable.

Medical, test and measurement, and aerospace and defense industries require cables that are reliable in harsh environments and are easy to terminate. Microwave cables with air-enhanced PTFE insulation achieve minimal loss characteristics, but these cables experience a "phase knee" effect at room temperature, meaning environments with temperature swings can affect cable performance. Temp-Flex foam-core ultra-low-loss coaxial microwave cable, with fluoropolymer insulation delivers stable performance at a range of temperatures while attaining competitive loss characteristics as compared with air-enhanced PTFE.

Space-constrained applications, such as medical and test and measurement, require cables that are not only stable in varying temperatures, but also have small outer diameters. Temp-Flex foam-core ultra-low-loss coaxial microwave cable offers sizes down to 1.194 mm shield OD, making it ideal for applications with strict space limitations. It is available in shielding ODs down to 1.194 mm (0.047"), allowing it to be used in space-constrained applications. It also offers a shielding effectiveness better than 100 dB at high frequency, providing high RF noise immunity and low EMI.
