Abstract:
A balanced filter suitable for a reduction of the filter size. The balanced filter comprises strip-line resonators (SL1a, SL1b) constituting resonance electrodes coupled to an unbalanced terminal, strip-line resonators (SL3a, SL3b) coupled directly to balanced side terminals and strip-line resonators (SL2a, SL2b) coupled to the balanced side terminals through impedance elements (Z).
