Abstract: A radio frequency (RF) amplification system or transmitter includes one or more power amplifiers and a controller that is configured to adjust amplitudes and phases of RF input signals of the one or more power amplifiers and supply voltages applied to the one or more power amplifiers. The system may include a single digital-to-RF modulator and a power divider to drive multiple power amplifiers. A power combiner may also be provided to combine outputs of the power amplifiers. In at least one implementation, amplitude adjustment of the RF input signals of the one or more power amplifiers may be used to provide transmit power control and/or power backoff.

Abstract: Described embodiments provide an integrated power supply and modulator system. The system includes a magnetic regulation stage, a switched-capacitor voltage balancer stage, and at least one output switching stage. The switched-capacitor voltage balancer stage is coupled to an output of the magnetic regulation stage, and maintains a substantially ratiometric set of voltages with respect to a reference potential. The magnetic regulation stage includes an inductor and at least two switches to selectively couple the inductor to two or more of (a) an input of the magnetic regulation stage, (b) a first voltage node of the switched-capacitor voltage balancer stage, and (c) a second voltage node of the switched-capacitor voltage balancer stage. The output switching stage selectively couples at least two voltages from the switched-capacitor voltage balancer stage to an output of the system in response to control signals. The system may include startup circuitry, feedback/feedforward circuitry, and control circuitry.

Abstract: Described embodiments provide a radio frequency (RF) amplifier system having at least one amplifier. The at least one amplifier includes an RF input port, an RF output port and a drain bias port. At least one voltage modulator is coupled to the bias port of the least one amplifier to provide a bias voltage. The bias voltage is selected by switching among a plurality of discrete voltages. At least one filter circuit is coupled between the at least one voltage modulator and the at least one amplifier. The at least one filter circuit controls spectral components resultant from transitions in the bias voltage when switching among the plurality of discrete voltages. A controller dynamically adapts at least one setting of the at least one voltage modulator by using multi-pulse transitions when switching among the plurality of discrete voltages for a first operating condition of the RF amplifier.

Abstract: Described embodiments provide a transmission-line resistance compression network that includes an input port, a first output port coupled to a first load and a second output port coupled to a second load. The first and second loads may have substantially similar input impedances under substantially similar operating conditions. The transmission-line resistance compression network includes a transmission-line network coupled to the input port, the first output port and the second output port, and includes at least two transmission lines of different lengths. For a first operating range, the resistances at input ports of the first and second loads vary over first and second ratios, respectively. The resistance of the input impedance at the input port of the transmission-line resistance compression network varies over a third ratio that is smaller than at least one of the first and second ratios.
