Abstract

PURPOSE:To damp the unneeded frequency band of higher harmonics, etc., by absorbing, by providing a filter at one part on the substrate of a peripheral mode type isolator. CONSTITUTION:On substrate 5 of a peripheral mode type isolator, wide line 6 is provided. In contact with tapered line part 6a at the output side of this line 6, dielectric resonator 9 is installed which resonates with a wave of a frequency twice a signal frequency. Consequently, a signal from input terminal 7 is under no influence of resonator 9 and appears at output terminal 8 at a low loss, but the double wave is reflected by resonator 9 and never appears at terminal 8 by being absorption-attenuated. Thus, the double wave is provided with passing characteristics of the absorptive-dampling type. The passing characteristics of the absorptive dampling type can be given to another frequency range by changing the shape of resonator 9.
