Abstract: Methods and systems for vector combining power amplification are disclosed herein. In one embodiment, a plurality of signals are individually amplified, then summed to form a desired time-varying complex envelope signal. Phase and/or frequency characteristics of one or more of the signals are controlled to provide the desired phase, frequency, and/or amplitude characteristics of the desired time-varying complex envelope signal. In another embodiment, a time-varying complex envelope signal is decomposed into a plurality of constant envelope constituent signals. The constituent signals are amplified equally or substantially equally, and then summed to construct an amplified version of the original time-varying envelope signal. Embodiments also perform frequency up-conversion.

Abstract: An electronic device includes an amplifier circuit coupled to a linearizer. The amplifier circuit may receive a first input signal including first and second frequencies and generate a first output signal including a delta frequency signal at a delta frequency, which is the difference between the first frequency and the second frequency. The linearizer includes a signal detector circuit, a current-mirror circuit, a low pass filter, a phase shifter, and a bias circuit. The signal detector circuit may generate a second output signal. The current-mirror circuit may adjust an amplitude of a signal. The low pass filter may eliminate a portion of the second output signal having frequencies greater than the delta frequency. The phase shifter may generate a feedback signal corresponding to the delta frequency signal. An amplitude and/or a phase of the feedback signal is different from an amplitude and/or a phase of the delta frequency signal.

Abstract: A plurality of carriers are divided into two systems, one on a low-frequency side and the other on a high-frequency side, a transmitting unit that executes processing for transmitting a signal wirelessly is provided in each of the two systems, and output lines of transmit amplifiers of each of the transmitting units are directly coupled and input to an antenna. A feedback unit on the low-frequency side feeds a low-frequency carrier signal portion contained in the transmit signal back to a distortion compensating unit on the low-frequency side, and a feedback unit on the high-frequency side feeds a high-frequency carrier signal portion contained in the transmit signal back to a distortion compensating unit on the high-frequency side. The distortion compensating units compensate for distortion on the low- and high-frequency sides.
