Vacuum and radiation are two primary elements that pose specific risks to RF cable performance in spaceflight applications. Therefore, it is critical to specify cables that will not outgas, resist multipaction as appropriate, withstand the radiation environment, and use materials that are not susceptible to whiskering.
There are three main types of orbit in space: Low Earth Orbit (LEO), Medium Earth Orbit (MEO), and Geosynchronous Orbit (GEO). LEO is orbit with an altitude at or below 2,000km; MEO is also known as Intermediate Circular Orbit (ICO) and is located above 2,000km but below 35,786km; GEO is located at 35,786km.
GEO and MEO satellites are typically used for:
LEO satellites are typically used for:
PhaseTrack® cable assemblies are designed for applications demanding minimal phase change over temperature. All PhaseTrack cables use a proprietary TF4™ dielectric that does not have the abrupt shift in the phase that occurs with solid- or tape-wrapped PTFE-based products under normal room ambient temperature conditions.
MaxGain Assemblies are high-performance, ultra-low loss microwave coaxial cables. Built with our unique spiral outer conductor technology, this light-weight cable is a reliable, high frequency interconnect solution.
InstaBend PhaseStable Assemblies are low-loss, highly flexible, foam-core micro coaxial cables, eliminating the PTFE change phase occurring around 19 ºC. Originally designed for space satellite programs, this high-performance cable has the same triple-shield construction as our popular SF®, SFT®, SilverLine®, and MilTtech® cables.
InstaBend Space Assemblies are flexible, coaxial microwave assemblies designed for interconnects between RF circuit cards, modules and enclosure panels. The cable can be bent very closely behind the connector, simplifying cable routing.
