A new series of waveguide to coax adapters covers a frequency range of 1.7 to 110 GHz in 22 waveguide bands. The line consists of 77 models in sizes of WR-10 to WR-430. These adapters are offered in a wide selection of waveguide flanges, sizes, and materials. They support 10 types of coax connectors and are available with UG (square/round cover), CMR, CPR, UDR, and PDR-style flanges. These waveguide to coax adapters deliver VSWR performance as low as 1.25:1 and are available with aluminum, gold-plated aluminum, gold-plated copper, or painted copper alloy finishes.
