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.
