Models PA-222F-EL are Q-Band waveguide to coax adapters that cover the frequency range of 33 to 50 GHz and constructed in end-launch or in-line 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 right angle versions are offered under the model numbers PA-222F-RA and PA-222M-RA.
