Compact and low-attenuation type directional microwave filter

摘要

The filter has a substrate 1 with a planar conductor structure in the way of a microwave circuit and within the substrate are formed two hollow waveguide filters 2,3 that have the characteristics of a directional filter. The filters have multiple resonator chambers 21-24,31-34 that have coupling orifices 25-28, 35-38. The exact number of resonators and orifices define the filter characteristics.
