Models PA-222F-RA & PA-222M-RA are Q-Band waveguide to coax adapters that cover the frequency range of 33 to 50 GHz and constructed in right angle configuration. These adapters offer excellent VSWRs at both coax & waveguide ends and thus extremely low insertion loss, allowing efficient transition between rectangular WR-22 waveguide and 2.4 mm coaxial connectors. The end launch versions are offered under the model numbers PA-222F-EL and PA-222M-EL.
