Abstract
A high pass filter includes: a first resonant circuit including an inductor and a capacitor in parallel between first and second terminals; a second resonant circuit including an inductor and a capacitor in series between a first end of the first resonant circuit and a ground; a third resonant circuit including an inductor and a capacitor in series between a second end of the first resonant circuit and the ground; a fourth resonant circuit disposed between the first end of the first resonant circuit and the first terminal, and including a first acoustic resonator; and a fifth resonant circuit disposed between the second end of the first resonant circuit and the second terminal, and including a second acoustic resonator. Attenuation regions respectively formed by the first, second, and third resonant circuits are arranged in lower frequency regions than attenuation regions respectively formed by the fourth and fifth resonant circuits.
