Abstract
Provided is a high-frequency amplifier capable of making a circuit substrate small and reducing a cost. A high-frequency amplifier is provided with a first substrate including a matching unit, and a second substrate including a transistor and a first impedance converter connected to each other, in which the matching unit of the first substrate and the first impedance converter are connected to each other via a first connection. Furthermore, the high-frequency amplifier is further provided with a third substrate including a matching unit, in which the second substrate may further include a second impedance converter connected to the transistor, and the second impedance converter and the matching unit of the third substrate may be connected to each other via a second connection.
