Abstract:
A high-frequency signal processing apparatus and a wireless communication apparatus can achieve a decrease in power consumption. For example, when an indicated power level to a high-frequency power amplifier is equal to or greater than a second reference value, envelope tracking is performed by causing a source voltage control circuit to control a high-speed DCDC converter using a detection result of an envelope detecting circuit and causing a bias control circuit to indicate a fixed bias value. The source voltage control circuit and the bias control circuit indicate a source voltage and a bias value decreasing in proportion to a decrease in the indicated power level when the indicated power level is in a range of the second reference value to the first reference value, and indicate a fixed source voltage and a fixed bias value when the indicated power level is less than the first reference value.

Claim (Index 1):
A wireless communication apparatus comprising:\n first and second power amplifying circuits coupled in parallel between an input node and an output node; a source voltage generating circuit; a bias supply circuit configured to supply a bias to the first and second power amplifying circuits; and an envelope detecting circuit configured to detect an envelope of an input signal input to the input node, wherein the source voltage generating circuit is configured to:\n supply a first source voltage to the first power amplifying circuit when the wireless communication apparatus is operating in a first power mode, the first source voltage varying along the envelope detected by the envelope detecting circuit, and \n supply a second source voltage when the wireless communication apparatus is operating in a second power mode, the second source voltage varying in proportion to an average power level of an output signal at the output node, and the second power mode being a lower power mode than the first power mode, and \n wherein the bias supply circuit is configured to:\n as a first operation, supply the bias to the first power amplifying circuit and not supply the bias to the second power amplifying circuit when the wireless communication apparatus is operating in the first power mode, and \n as a second operation, supply the bias to the second power amplifying circuit and not supply the bias to the first power amplifying circuit when the wireless communication apparatus is operating in the second power mode.
