To optimize power efficiency of each of multiple types of power in a receiver that converts a radio signal received through an antenna into the multiple types of power.SOLUTION: A receiver includes: a first matching circuit configured to receive, through a branch point, antenna input power that is input from an antenna in accordance with a radio signal received by the antenna and input a portion of the received antenna input power to a first circuit as first input power, an impedance of the first matching circuit decreasing as the antenna input power increases; and a second matching circuit configured to receive, through the branch point, the antenna input power, and input another portion of the received antenna input power to a second circuit as second input power, an impedance of the second matching circuit increasing as the antenna input power increases.SELECTED DRAWING: Figure 1 【課題】アンテナを介して受信する無線信号を複数の電力に変換する受信器において、複数の電力の電力効率をそれぞれ最適にする。【解決手段】受信器は、アンテナで受信する無線信号に応じて前記アンテナから入力されるアンテナ入力電力を分岐点を介して受信し、受信した前記アンテナ入力電力の一部を第１入力電力として第１回路に入力し、前記アンテナ入力電力が大きくなるにしたがいインピーダンスが下がる第１整合回路と、前記アンテナ入力電力を前記分岐点を介して受信し、受信した前記アンテナ入力電力の別の一部を第２入力電力として第２回路に入力し、前記アンテナ入力電力が大きくなるにしたがいインピーダンスが上がる第２整合回路と、を有する。【選択図】図１
