摘要： A circuit comprises a delay module that receives a digital transmit signal and that generates a delayed transmit signal. A first digital to analog converter converts the delayed transmit signal to an analog transmit signal. An analog output circuit amplifies the analog transmit signal. An envelope generating module generates an envelope signal based on amplitude information in the digital transmit signal. A supply adjustment module supplies a voltage supply reference when the envelope signal is less than a threshold and boosts the bias voltage of the analog output circuit above the voltage supply reference when the envelope signal is greater than the threshold.

摘要： A power amplifier module comprises a power amplifier circuit having an output power level controlled by a power supply voltage. A power supply transistor controls the power supply to the power amplifier circuit from a drive signal which is received from a drive circuit. The drive circuit generates the drive signal in response to a power level input signal, which specifically may correspond to a power ramping for a GSM cellular communication system. The power amplifier module furthermore comprises a detection circuit which determines an operating characteristic of the power supply transistor. The operating characteristic is preferably a saturation characteristic. A control circuit controls the drive signal in response to the operating characteristic. The control circuit preferably controls the drive signal such that the power supply transistor does not enter the linear region for a Field Effect Transistor and the saturated region for a bipolar transistor.

摘要： A power supply for providing a modulated output voltage to a load is disclosed. According to various embodiments, the power supply comprises a plurality of parallel-connected switch-mode power modules and a controller. The controller is connected to each of the power modules and is for controlling the duty cycles of the respective power modules such that the power modules have a common duty cycle in steady state, but in a phase-shifted or “interleaved” manner. In addition, the controller is for controlling the output voltage of the power converter by controlling the ratio of power modules in the forward state at a time to the total number of power modules. In this way, by providing a sufficiently large number of power modules, arbitrarily low output voltage amplitudes and intra-level oscillations can be achieved. Further, the rate of modulation of the output voltage can exceed the switching frequency (f=1/T, where T is the switching period) of the power modules. An rf power amplifier system including such a power supply is also disclosed.

摘要： A radio-frequency power amplifier is supplied by a voltage supply device. The voltage supply device has a voltage divider chain that is connected at the input side with a base potential and a ground voltage. The voltage divider chain has a number of Zener diodes connected in series, with which at least one capacitor is connected in parallel. Intermediate voltages that lie between the ground voltage and the base potential can be tapped at respective node points between each two immediately adjacent Zener diodes. A first supply input of the radio-frequency power amplifier is connected with the ground voltage. The voltage divider chain is connected with the radio-frequency power amplifier via a switching device. The switching device has a number of switching elements connected in parallel with one another, these switching elements being connected at the output side with a second supply input of the radio-frequency power amplifier. The base potential or one of the intermediate voltages is present at the input side of each switching element. The switching elements can be individually controlled by a control device, such that the second supply input can be selectively connected with the base potential and each of the intermediate voltages via the switching device.
