Abstract
In a semiconductor device, when a first surface of a first member is viewed in plan, at least one switch circuit including a switch is disposed within the first surface. A second member is joined to the first surface of the first member in surface contact with the first surface. The second member includes a plurality of transistors that are made of a compound semiconductor and form a radio-frequency amplifier circuit. A first conductive protrusion protrudes from the second member on an opposite side to the first member. The first member includes a circuit element disposed between the radio-frequency amplifier circuit and the at least one switch circuit in a plan view, the circuit element not forming the switch circuit.
