ABSTRACT:
Architectures including digital outphasing transmitters. Digital signal generation circuitry generates at least two base-band sinusoid signals. Bandpass modulation circuitry is coupled to receive the base-band sinusoid signals and generates at least two modulated digital signals. Power amplifiers are coupled to receive the modulated digital signals to amplify the modulated digital signals. The amplified modulated signals are combined and transmitted.
