Abstract: Apparatus and methods for an inverted Doherty amplifier operating at gigahertz frequencies are described. RF fractional bandwidth and signal bandwidth may be increased over a conventional Doherty amplifier configuration when impedance-matching components and an impedance inverter in an output network of the inverted Doherty amplifier are designed based on characteristics of the main and peaking amplifier and asymmetry factor of the amplifier.

Abstract: Apparatus and methods for a low-load-modulation power amplifier (500) are described. Low-load-modulation power amplifiers can include multiple amplifiers connected in parallel to amplify a signal that has been divided into parallel circuit branches. One of the amplifiers can operate as a main amplifier (132) in a first amplification class and the remaining amplifiers can operate as peaking amplifiers (538, 539) in a second amplification class. The main amplifier (132) can see low modulation of its load between the power amplifier's fully-on and fully backed-off states. Improvements in bandwidth and drain efficiency over conventional Doherty amplifiers are obtained.

Abstract: Apparatus and methods for an improved-efficiency Doherty amplifier are described. The Doherty amplifier may include a two-stage peaking amplifier that transitions from an "off" state to an "on" state later and more rapidly than a single-stage peaking amplifier used in a conventional Doherty amplifier. The improved Doherty amplifier may operate at higher gain values than a conventional Doherty amplifier, with no appreciable reduction in signal bandwidth.

Abstract: Apparatus and methods for a modified Doherty amplifier operating at gigahertz frequencies are described. The combining of signals from a main amplifier (132) and a peaking amplifier (138) occur prior to impedance matching of the amplifier's output to a load. An integrated distributed inductor (510) may be used in an impedance inverter to combine the signals.

Abstract: Apparatus and methods for a modified Doherty amplifier operating at gigahertz frequencies are described. The combining of signals from a main amplifier and a peaking amplifier occur prior to impedance matching of the amplifier's output to a load. An integrated distributed inductor may be used in an impedance inverter to combine the signals. A size of the impedance element can be selected by patterning during manufacture to tune the amplifier and to allow power scaling for the amplifier.

Abstract: Apparatus and methods for a no-load-modulation power amplifier are described. No-load-modulation power amplifiers can comprise multiple amplifiers connected in parallel to amplify a signal that has been divided into parallel circuit branches. One of the amplifiers can operate as a main amplifier in a first amplification class and the remaining amplifiers can operate as peaking amplifiers in a second amplification class. The main amplifier can see essentially no modulation of its load between the power amplifier's fully-on and fully backed-off states. The power amplifiers can operate in symmetric and asymmetric modes. Improvements in bandwidth and drain efficiency over conventional Doherty amplifiers are obtained. Further improvements can be obtained by combining signals from the amplifiers with hybrid couplers.

Abstract: Apparatus and methods for a modified Doherty amplifier operating at gigahertz frequencies are described. The combining of signals from a main amplifier (132) and a peaking amplifier (138) occur at a combining node prior to impedance matching of the amplifier's output to a load. An impedance inverter (410) comprises a first integrated distributed inductor and a second integrated distributed inductor connected by a capacitor (580), wherein the impedance inverter (410) is connected between an output of the main amplifier (132) and the combining node.
