contents DECEMBER 2014 PChoavseer -immaatgceh; e d cable assemblies to 50 GHz Rated for operation from DC to 50 GHz, a range of phase matched cable assemblies allows engineers to specify electrical length in time or degrees at the frequency of operation, for a specific cable assembly. Cables can be matched in “sets” or pairs. One of two methods may be used - electrical length (matched to a golden standard), or phase matched to another cable. Typical applications include high power amplifiers, RF combiners and filters, multi-beam antenna arrays, phased array radars. Intelliconnect can provide bespoke cable assemblies for both high-volume or specialist small batch requirements operating from DC to 50GHz for RF applications including test and measurement and defence. Coaxial, triaxial and multi-way connectors may be specified and fully immersible waterproof versions are available; phase matching is available to ensure signal integrity in individual, or batches of, assemblies.
