摘要： The present disclosure relates to an RF power amplifier (PA) power supply that includes a series pass circuit coupled across a direct current (DC)-to-DC converter to receive a power supply input signal, such as provided from a battery, to provide a power supply output signal to at least a first RF PA based on an output setpoint. Control circuitry selects between a switching supply operating mode and a non-switching supply operating mode based on the output setpoint. During the switching supply operating mode, the DC-to-DC converter provides the power supply output signal and during the non-switching supply operating mode, the series pass circuit provides the power supply output signal.

摘要： Embodiments of the present invention include amplitude-modulated or polar-modulated radio frequency (RF) power amplifier circuitry, in which an envelope power supply input to an RF power amplifier is powered by a pre-distorted amplitude modulation (AM) power supply. The pre-distorted AM power supply receives an AM signal, which is then pre-distorted and amplified to provide an AM power supply signal to the RF power amplifier. The pre-distortion of the AM signal is used to improve the linearity, the efficiency, or both, of the RF power amplifier. The pre-distortion provides a feed-forward system, which may allow use of a reduced bandwidth pre-distorted AM signal to an AM power supply and a reduced bandwidth AM power supply, which may increase efficiency.

摘要： Power control circuitry is provided for controlling an output power of a transmitter of a mobile terminal operating according to a continuous time transmit scheme such as Wideband Code Division Multiple Access (WCDMA). Transmit circuitry processes a quadrature baseband signal to provide a radio frequency transmit signal. The radio frequency transmit signal is coupled to the power control circuitry via a coupler and processed to provide a feedback amplitude signal. The power control circuitry operates to remove an amplitude modulation component from the feedback signal using a reference amplitude signal generated from the quadrature baseband signal, thereby providing a measured gain signal of the transmit circuitry. Based on the measured gain signal and a target output power, the power control circuitry operates to control a gain of the transmit circuitry such that the output power of the transmit circuitry is within a predetermined range about the target output power.

摘要： A transceiver may include an antenna tuning control system operably associated with an antenna tuner to control the current power levels of the transmission signal and the receive signal. The antenna tuner control system may receive transmit power control (TPC) information, which was transmitted to the transceiver from a base station on the receive signal. The TPC information may be utilized to change the current power level of the transmission signal to a desired transmission power level. In addition, the antenna tuner control system may generate receive power control (RPC) information. The RPC information may be utilized to change the current power level of the receive signal to a desired receive power level. The antenna tuner control system is operable to adjust the pass band in accordance with the TPC information and the RPC information.

摘要： An antenna tuner provides a pass band with a transmission resonant frequency and a receive resonant frequency. In this manner, the pass band of the antenna tuner can simultaneously provide matching at both a transmission frequency and a receive frequency, when both transmission signals and receive signals are received on the same antenna. The antenna tuner includes a first capacitive element that is coupled to series resonate with the antenna and a low-pass pi network.

摘要： Embodiments of the present disclosure relate to radio frequency (RF) transmitter circuitry, which includes non-inverting path power amplifier (PA) circuitry, inverting path PA circuitry, and RF transformer circuitry. The non-inverting path PA circuitry provides a non-inverting RF signal and a first power supply (PS) signal to the RF transformer circuitry, such that the first PS signal has a first ripple voltage. The inverting path PA circuitry provides an inverting RF signal and a second PS signal to the RF transformer circuitry, such that the second PS signal has a second ripple voltage. The RF transformer circuitry additively combines the non-inverting RF signal and the inverting RF signal to provide an RF output signal, such that effects of the first ripple voltage and the second ripple voltage are substantially cancelled from the RF output signal.
