Abstract(English):

The invention relates to a switched mode power amplifier with an ideal IQ combining. An I converter (502) outputs I sign data and I magnitude data based on received I data. A Q converter (504) outputs Q sign data and Q magnitude data based on received Q data. An I clock (406) generates an I phase based ort the I sign data. A Q clock generates a Q phase based on the Q sign data. An I modulator (514) generates an I magnitude pulse stream based on the I magnitude data. A Q modulator (516) generates a Q magnitude pulse stream based on the Q magnitude data. A digital logic component (518) generates an output signal based on the I phase, the I magnitude pulse stream, the Q phase and the Q magnitude pulse stream. A power amplifier (526) generates an amplified signal based on the output signal.
