Patent ID: 7539269

Claim:
A power synthesizer comprising a plurality of n stages in parallel with one another, wherein n is an integer at least equal to two, each of the n stages comprising: a modulator and a discrete amplitude amplifier in series with one another, each n th discrete amplitude amplifier configured to apply a gain that is unique as compared to all other of the discrete amplitude amplifiers; and a common actuator configured to simultaneously switch the n modulators, wherein each of the modulators is coupled to the common actuator, and each n th discrete amplitude amplifier is configured to output a signal amplitude a 0 /2 n−1 , where a 0 is a maximum signal amplitude output by any of said n discrete amplitude amplifiers; the power synthesizer further comprises a discrete amplitude generator configured to convert a real valued input to a first and second parallel binary outputs that are each coupled to an input of a respective one of the n modulators.
