摘要： A wireless communication apparatus, which is designed to control the output power without using the power control signal sent from the base station, comprises a high-frequency power amplifier for transmission, a detection means which measures the output power of the power amplifier, and an automatic power control circuit which controls the output power of the power amplifier based on information provided by the detection means. The power amplifier includes an amplifying system which has multiple amplifying stages and is connected between the input and output terminals, and bias circuits which supply bias voltages to transistors of the respective amplifying stages. The bias circuits, which supply the bias voltages to the multiple amplifying stages excluding the last amplifying stage, are each made up of multiple resistors. Each of these bias circuits divides with the resistors the voltage of the entered power control signal to produce a bias voltage, which has a linear response to the control signal for low-power mode, to be fed to the control terminal of the amplifying stage. The bias circuit which supplies a bias voltage to the last amplifying stage includes a circuit which produces a bias voltage which has a nonlinear response to the control signal for high-power mode.

摘要： A module including a bias circuit that generates gate bias voltages by resistance dividers creates a problem in that the values of the resistances constituting the bias circuit must be finely adjusted, and accordingly extra trimming tasks are required. The present invention provides current generators that generate currents varying with desired characteristics responsive to a control voltage, independent of variations in transistor threshold voltages, connects output resistors to parallel transistors in respective stages to form current mirror circuits, and supplies currents from the current generators thereto to drive them, instead of supplying dividing voltages.
