Abstract
A high-frequency module () includes a reception-side filter () that uses a first frequency band as a pass band and a second frequency band as an attenuation band, an LNA (), and a matching circuit () disposed between the reception-side filter () and the LNA (). In a Smith chart, the matching circuit () makes an interval between impedance in the second frequency band of the reception-side filter () and a second gain circle center point indicating impedance at which gain in the second frequency band of the LNA () is maximized greater than an interval between impedance in the first frequency band of the reception-side filter () and a first gain circle center point indicating impedance at which gain in the first frequency band of the LNA () is maximized.
