Abstract: A power amplification device includes a first member in which a first circuit is formed, a second member in which a second circuit is formed, and a member-member connection conductor that electrically connects the first circuit and the second circuit to each other. The second member is mounted on the first member. The second circuit includes a first amplifier, which amplifies a radio frequency signal to output a first amplified signal. The first circuit includes a control circuit that controls an operation of the second circuit. At least part of a first termination circuit, which is connected to the first amplifier through the member-member connection conductor and which attenuates a harmonic wave component of the first amplified signal, is formed in the first member.

Abstract: A semiconductor apparatus includes a substrate, plural transistor groups disposed on the substrate, an insulating film, and a metal member. Each of the plural transistor groups includes plural unit transistors arranged in a first direction within a plane of a top surface of the substrate. The plural transistor groups are arranged in a second direction perpendicular to the first direction. The insulating film covers the plural unit transistors and includes at least one cavity. The metal member is disposed on the insulating film and is electrically connected to the plural unit transistors via the at least one cavity. A heat transfer path is formed by a metal in a region from each of the plural unit transistors to a top surface of the metal member. Thermal resistance values of the heat transfer paths are different from each other among the plural unit transistors.
