Abstract: An apparatus of a hybrid power modulator using interleaving switching is provided. The apparatus includes a linear switching unit for generating an output signal by comparing an envelope input signal and a feedback signal, an interleaving signal generator for generating an interleaving switching signal arranged not to supply the signal to input stages of P-type Metal-Oxide-Semiconductor (MOS) Field Effect Transistors (FETs) and N-type MOS FETs of power cells at the same time by comparing the output signal and a reference signal, and a switching amplifying unit for determining a level of the switching signal using the interleaving switching signal. Hence, the hybrid power modulator using the interleaving switching method in the envelope signal of the wide bandwidth maintains high efficiency and high linearity. In addition, the buck converter can use the single inductor by preventing the simultaneous on/off of the power cells.

Abstract: An apparatus and method for improving the efficiency of a power supply modulator for modulating a supply voltage of a power amplifier are provided. The apparatus for generating a supply voltage includes a Switching Mode Power Supplier (SMPS) module for generating a current of a power supply signal, and a linear regulator for generating a source current for supplementing an insufficient amount of the current generated by the SMPS module and a sink current for eliminating an excessive amount of the current generated by the SMPS module. The SMPS module generates the current of the power supply signal by selecting at least one of a plurality of power supplies that have different voltages according to a voltage level of an input signal of the SMPS module.

Abstract: A transmit apparatus having a supply modulator is provided. The apparatus includes a detector and the supply modulator. In the method, the detector detects an output signal of the supply modulator. Also, the supply modulator receives the detected output signal of the supply modulator from the detector and calibrates a modulation characteristic of the supply modulator. The transmit apparatus having a supply modulator includes a modulator/demodulator (modem) and the supply modulator. The modem provides a calibration signal for calibrating a modulation characteristic of the supply modulator, to the supply modulator. The supply modulator outputs a modulated signal in accordance with the calibrated modulation characteristic of the supply modulator based on the calibration signal from the modem.
