Abstract
An amplifying apparatus includes a transistor arranged on a substrate and constituting an amplifier, an input terminal for inputting a high-frequency signal to the amplifier, an output terminal for outputting the high-frequency signal amplified by the amplifier, a first inductor formed in or on the substrate and connected between a source of the transistor and a ground, and a second inductor formed in or on the substrate and connected between a gate of the transistor and the input terminal. When the substrate is viewed in a plan view, the first inductor and the second inductor do not overlap each other. The first inductor and the second inductor are magnetically coupled to each other.
