The FMWCA1022 is a waveguide to coaxial adapter designed to transition signals between a WR-42 waveguide and an SMA female coaxial interface. It operates over a frequency range of 18 GHz to 26.5 GHz with a maximum VSWR of 1.3:1 and a maximum insertion loss of 0.3 dB. This right-angle adapter features a UG-597/U square cover flange and is constructed from chem-filmed aluminum for durability and repeatable RF performance. It is commonly used in applications such as test benches, radar, satellite, and microwave radio systems.
