First Claim
1. A filter circuit comprising:
- a first band-pass filter, a second band-pass filter, a third band-pass filter and a fourth band-pass filter each having an input terminal and an output terminal;
a first terminal to which one of the input terminal and the output terminal of the first band-pass filter and one of the input terminal and the output terminal of the second band-pass filter are connected in common;
a second terminal to which one of the input terminal and the output terminal of the third band-pass filter and one of the input terminal and the output terminal of the fourth band-pass filter are connected in common;
a third terminal to which another one of the input terminal and the output terminal of the first band-pass filter and another one of the input terminal and the output terminal of the fourth band-pass filter are connected in common; and
a fourth terminal to which another one of the input terminal and the output terminal of the second band-pass filter and another one of the input terminal and the output terminal of the third band-pass filter are connected in common.
