MULTI-LEVEL PULSE MODULATED POLAR TRANSMITTER AND METHOD OF GENERATING MULTI-LEVEL MODULATED ENVELOPE SIGNALS CARRYING MODULATED RF SIGNAL

摘要

A multi-level pulse modulated polar transmitter and a method of generating multi-level pulse modulated RF signals carrying phase information, in conjunction with a plurality of power amplifiers, so as to enhance the bandwidth of the transmitter and to reduce spurious emission and noise while synchronizing the phase and envelope of the input signals.
