摘要: A bandpass filter disposed on a substrate includes one pair of ring Each of the ring resonators includes a pattern inductor, a resonance capacitor connected in parallel with the pattern inductor, and an input/output terminal connected with the pattern inductor via a coupling capacitor. The pattern inductors are connected with an impedance varying device, whereby the bandpass filter is capable of frequency adjustments.
