Abstract
The invention provides a high-frequency composite unit, wherein: a two-terminal switch constituting a transmission section, an LC filter, and a notch filter are connected between a first terminal and a second terminal; and said two-terminal switch, said LC filter, and said notch filter are integrated into a layered structure in which a plurality of dielectric layers are stacked. The above high-frequency composite unit has high performance, which can handle high-frequency signals of multiple frequency bands that are relatively adjacent.
