EIA Standard Circular WG to Rectangular Waveguide
A-INFO's circular to rectangular waveguide transitions cover the frequency range up to 170 GHz in several waveguide bands. The waveguide transitions are used to connect standard EIA rectangular waveguide to EIA circular waveguide with a low loss and reflection. Transitions are also available in customer specific circular waveguide size and lengths.
