Interdigitated, laminated LC bandpass filter with different length electrodes
A band pass filter includes LC resonators defined by laminated layers and is constructed such that the resonant frequencies of the LC resonators shift in the same direction when laminated layers deviate from each other. In the arrangement of the band pass filter, the inductor pattern of a first LC resonator and the capacitor pattern of a second LC resonator are disposed on a surface of a first ceramic sheet. The inductor pattern and the capacitor pattern extend to the same side of the first ceramic sheet. In addition, the capacitor pattern of the first LC resonator and the inductor pattern of the second LC resonator are disposed on a surface of a second ceramic sheet. The capacitor pattern and the inductor pattern extend to the same surface of the second sheet.
