Abstract
The present disclosure relates to a low-complexity transmitter architecture that drives phase modulators with digital signals to generate a pulse width modulated (PWM) signal that is transmitted by an antenna. In some embodiments, the system has a pre-processing element that generates first and second digital control signals from a digital baseband signal. A first phase modulation component introduces a first phase shift into a first local oscillator signal based upon the first control signal and generates a first digital signal corresponding to the first phase shift. A second phase modulation component introduces a second phase shift into the first local oscillator signal based upon the second control signal and generates a second digital signal corresponding to the second phase shift. A combination element is configured to combine the first and second digital output signals to generate an RF pulse width modulated (RF-PWM) signal.
