Abstract
Provided are a higher-order mode suppressor, a waveguide filter device using the same, a spectrum analyzer, a signal analyzer, a signal generation device, a higher-order mode suppression control method, and a filter configuration method, which can reliably prevent a passage of an occurring higher-order mode with a simple structure, and which can realize highly reliable spectrum measurement, signal analysis, and signal generation which are not affected by the higher-order mode, by applying the structure. In a higher-order mode suppressor, a ridge waveguide portion is configured with dimensions such that an inner diameter of a waveguide path is narrower than inner diameters of waveguide paths of waveguides, and when a frequency band including a basic frequency band is input from an input side, the higher-order mode occurring on the input side is suppressed with respect to a frequency band of twice or more than a cutoff frequency.
