About RG405
RG-405 (UT-085) is a 0.086" semi-rigid coaxial cable — smaller than RG-402 — with a solid copper outer conductor delivering superior shielding and phase stability. Commonly used in microwave integrated circuit (MMIC) assemblies, millimeter-wave test setups, and anywhere an extremely compact rigid interconnect is required up to 65 GHz.
