Abstract
In a high-frequency amplifier for amplifying transmission and reception signals, an integrated circuit area is reduced to reduce production costs. A high-frequency amplifier () includes a reception signal amplifying part (), a transmission signal amplifying part (), and a spiral inductor (). An output of the reception signal amplifying part () is connected with an output of the transmission signal amplifying part () to be an output terminal OUT of the high-frequency amplifier (). The single spiral inductor () is connected to the output terminal OUT. This spiral inductor () is used as a load common to the reception signal amplifying part () and the transmission signal amplifying part (). Thereby, the area of the integrated circuit is reduced, and the production cost is reduced.
