SYSTEMS AND METHODS FOR VECTOR POWER AMPLIFICATION

摘要

A method of amplifying and frequency up-converting baseband signals comprising: accepting an input clock (510) at a frequency that corresponds to the desire output frequency; independently amplifying (562) baseband in-phase (I vector) envelope and phase information at the desired output frequency; independently amplifying (564) baseband quadrature (Q vector) envelope and phase information at the desired output frequency; summing (572) the amplified baseband in-phase and quadrature information to produce the desired waveform on the desired frequency.
