Abstract

A high-frequency filter () includes a first input-output terminal (P), a second input-output terminal (P), a variable frequency filter (), and a fixed frequency filter (). The variable frequency filter () and the fixed frequency filter () are connected in series and coupled between the first input-output terminal (P) and the second input-output terminal (P). The variable frequency filter () is a filter capable of varying a passband and an attenuation band. The fixed frequency filter () is a filter having a fixed passband and a fixed attenuation band. The passband of the fixed frequency filter () is set so as to be at least partially overlapped with multiple passbands realized by the fixed frequency filter ().
