This paper describes a novel alternating and outphasing modulator for the generation and amplification of a linear modulation signal. The architecture requires a linear modulation signal to be represented as two outphasing signals with a constant envelope, which are alternating or switching at the input of two nonlinear amplifiers to produce a linear modulation signal. A power combiner can be employed to cancel the mixed components due to the switching. This will minimize the requirements of the output filter, and hence, simplified the design. This new modulation architecture is simple, and hence, is suitable for all-digital integration. The measurement results of the wideband code division multiple access signal are presented and compared with a conventional linear amplification with nonlinear components architecture.
