PURPOSE:To enlarge an isolation against a spurious component without deteriorating a receiving sensitivity by providing a resonator to a spurious frequency in a high power limiter. CONSTITUTION:A high power limiter 100 formed by a waveguide is formed by a waveguide type limiter 110 and a cavity type resonator 120. This resonator 120 is provided with an adjusting plate 121 for adjusting a resonance frequency. In this state, an atenuation of only a spurious component can be enlarged, and an insertion loss to a main frequency can be reduced by aligning a resonance frequency of the resonator 120 with a spurious frequency by the adjusting plate 121. In this way, an isolation against the spurious component can be enlarged without deteriorating a receiving sensitivity. |
