Sealflex 2 microwave cable assemblies are designed for applications requiring consistent microwave performance through to 18 GHz and may be used with minimal degradation to 26 GHz with SMA connectors.
All connector designs exhibit “mode free” characteristics to 18 GHz, thereby allowing low VSWR to be specified without “spikes” being present in the upper frequency spectrum. Each assembly is 100% tested for VSWR and insertion loss and test plots are supplied with each item. Sealflex 2 assemblies have been adopted for use in various avionic systems, missiles, military ground and ship borne applications as well as commercial communications equipment.
