ABSTRACT:
A high frequency filter incorporates: an unbalanced input/output terminal; two balanced input/output terminals; two resonators respectively provided between the unbalanced input/output terminal and the two balanced input/output terminals; and a layered substrate for integrating components of the high frequency filter. The two resonators are inductively coupled to each other, and are also capacitively coupled to each other through two capacitors. Each of the two capacitors is formed using a pair of first and second electrodes and a dielectric layer. The first electrode is connected to one of the resonators via a through hole. The second electrode is connected to the other of the resonators and opposed to the first electrode forming the pair with the second electrode, the dielectric layer being disposed between the second electrode and the first electrode.
