Abstract:
A switch-modulator for a radio-frequency power amplifier, arranged to modulate the I-signal and the Q-signal of the complex components (I+j·Q) separately in an I-signal part and a Q-signal part in order to create a modulated I-signal pulse sequence and a modulated Q-signal pulse sequence, wherein the modulation comprises a time-shift of the pulse positions within a sample interval.
