Abstract
A composite board includes a first member and a second member on a first surface that is one surface of the first member. A first conductor protrusion protrudes from the second member in a direction in which the first surface faces. A second conductor protrusion protrudes from the composite board in the direction in which the first surface faces. The first member includes a first semiconductor board, and the second member includes a second semiconductor board having lower thermal conductivity than the first semiconductor board. A radio frequency amplifier circuit including first transistors is in the second member. The first conductor protrusion is electrically connected to the first transistors and at least partially overlaps with the first transistors in a plan view of the first surface. The composite board includes a connection part that reaches the first semiconductor board or the second semiconductor board from the second conductor protrusion.
