This paper presents a transmitter architecture based on a pulse-modulated polar transmitter using multiphase pulsewidth modulation. The modulation to the radio-frequency input signal, instead of conventional drain modulation, significantly reduces the circuit complexity, while the multiphase modulation technique reduces the out-of-band emissions.

This paper presents an architecture for implementing a wide dynamic range pulse-modulated polar transmitter and its system-level requirements. For validation of the proposed architecture, a simulation platform is constructed using a CDMA2000 1X signal. The system level simulation results show that the architecture can achieve over 80-dB dynamic range easily(More)
