Abstract
For use in a transmitter in a wireless network, a transmitter apparatus is configured for digital multi-level outphasing. The apparatus includes a bandwidth reduction (BWR) modulator block configured to receive a phase modulated carrier and reduce a bandwidth of the phase modulated carrier using amplitude modulation. The apparatus also includes an outphasing modulator block configured to receive the reduced-bandwidth phase modulated carrier and an amplitude modulated signal, and convert the reduced-bandwidth phase modulated carrier into a plurality of phase modulated signals. The apparatus further includes an amplification stage comprising a plurality of power transistors configured to amplify the phase modulated signals.
