Abstract

PURPOSE:To suppress the spurious response, by using two types or more of resonators different from spurious resonance frequency and equal in the basic resonance frequency. CONSTITUTION:Resonator 73-76 of transmission line of both end open type are composed of uniform line resonators 73, 76 and resonators selecting the impedance ratio K as smaller than 1, and this is achieved by combining two or more resonators different in the shape. But, the basic resonance frequency must be the same. Further, by using the characteristics that the spurious resonance frequency can arbitrarily be set through the change in K even with the basic frequency designed the same, a band pass filter is constituted by combining resonators differnt from K, to improve the blocking region characteristics.
