Abstract
An input signal Sx in a first millimeter-wave frequency band higher than 100 GHz is input to a millimeter-wave band filterin which a pair of radio wave half mirrorsA andB so as to opposite to each other and which performs a resonance operation. A signal component Sa corresponding to the resonance frequency of the filter is extracted, is mixed with a first local signal Lwith a fixed frequency, and is converted into a signal in a second frequency band. The converted signal component Sb is mixed with a second local signal Lwhose frequency is swept and is converted into a signal in a predetermined intermediate frequency band. Then, the level of the signal is detected. The millimeter-wave filterhas high selectivity characteristics in a frequency domain higher than 100 GHz and can change its passband center frequency.
