Abstract
Provided is a wireless communication device in which an antenna switch module is omitted. The wireless communication device includes a PA that amplifies a transmission signal, a transmission circuit that processes the amplified transmission signal, an antenna, and a control unit that alternately activates and deactivates the PA, the transmission circuit being configured to match an impedance between the transmission circuit and the antenna when the PA is activated, and to put an impedance as seen from the antenna toward the transmission circuit when the PA is deactivated in a high impedance state.
