Claims

[Scope of utility model registration request]

In a filter in which a waveguide-type low-pass filter and a band-pass filter are connected in cascade, the low-pass filter main body and the band-pass filter are composed of a thin waveguide. A coaxial waveguide converter that functions as a converter between a thin waveguide and coax is used as the converter of the low-pass filter at the connection with the bandpass filter, and a coaxial waveguide converter is used for the bandpass filter as well. A waveguide type bandpass filter characterized in that a tube converter is connected and both coaxial waveguide converters are coupled by a coaxial tube or a coaxial cable.
