Patent ID: 7928801

Claim:
An amplification system, comprising: a plurality of amplifiers, wherein each of the amplifiers belongs to a same amplifier type and each of the amplifiers is configured to amplify a respective input signal into a respective amplified output signal; a plurality of input coefficient units configured to apply input coefficients to the input signals of the plurality of amplifiers, wherein each of the input coefficient units applies an input coefficient w in,n to the input signal of one of the plurality of amplifiers, the input coefficient w in,n given by w in,n =e jα(n−1)π/N where α is a first parameter, n is an integer from 1 to N where N is a number of the plurality of amplifiers and n is different for each of the input coefficient units; a plurality of output coefficient units configured to apply output coefficients to the amplified output signals of the plurality of amplifiers; and a signal combiner configured to combine the amplified output signals into a single amplified output signal, wherein the input and output coefficients applied to the input signals and the amplified output signals of the plurality of amplifiers suppress non-linear products when the amplified output signals are combined into the single amplified output signal.
