摘要

The level of suppression in the disclosed balanced filter is improved by eliminating unneeded in-phase components and canceling an imbalance in bridging capacitance that exists between an input terminal and two output terminals. The balanced filter is provided with an input terminal, a filter element that filters a signal input into the input terminal, and a first output terminal and a second output terminal that differentially output a signal from the filter element, and a capacitor is connected between the input terminal and one output terminal of the first output terminal and the second output terminal.
