Abstract
A high pass filter includes a first LC series resonator including a first end connected to a signal path, and a second end connected to at least one ground terminal, a second LC series resonator including a third end electrically connected to the signal path, and a fourth end connected to the at least one ground terminal, and a third capacitor between a first portion extending from a first capacitor to a first inductor and a second portion extending from a second capacitor to a second inductor.
Claims19
A high pass filter comprising:
- a first input and output terminal;
- a second input and output terminal;
- at least one ground terminal;
- a signal path disposed between the first input and output terminal and the second input and output terminal;
- a first inductor;
- a first capacitor;
- a first LC series resonator including a first end electrically connected to the signal path, a second end electrically connected to the at least one ground terminal, the first inductor, and the first capacitor;
- a second inductor;
- a second capacitor;
- a second LC series resonator including a third end electrically connected to the signal path, a fourth end electrically connected to the at least one ground terminal, the second inductor, and the second capacitor;
- and
- a third capacitor provided between a first portion and a second portion, the first portion extending from a first electrode of the first capacitor that is electrically connected to the first inductor to a portion of the first inductor closer to the first electrode than an end of the first inductor that is not electrically connected to the first capacitor, the second portion extending from a second electrode of the second capacitor that is electrically connected to the second inductor to a portion of the second inductor closer to the second electrode than an end of the second inductor that is not electrically connected to the second capacitor.
