ABSTRACT:
Systems and methods for achieving linear amplification with high efficiency are provided. An input signal is amplified using a plurality of amplifiers by dividing the input signal into a plurality of inputs signals, amplifying the plurality of input signals with the plurality of amplifiers and combining the amplified output signals of the plurality of amplifiers into a single amplified output signal. Coefficients are applied to the input signals and the amplified output signals of the amplifiers so that non-linear products due to the amplifiers are suppressed when the amplified output signals of the amplifiers are combined into the single amplified output signal. The suppression of the non-linear products allows an amplification system to achieve linear amplification using high efficiency non-linear amplifiers. The systems and methods can also be applied to other non-linear devices, for example, mixers and modulators, to suppress non-linear products in these devices.
