POLAR LOOP CIRCUIT ARRANGEMENT WITH DISTORTION SUPPRESSION AND METHOD FOR DISTORTION SUPPRESSION IN A POLAR LOOP CIRCUIT ARRANGEMENT

POLAR LOOP CIRCUIT ARRANGEMENT WITH DISTORTION SUPPRESSION AND METHOD FOR DISTORTION SUPPRESSION IN A POLAR LOOP CIRCUIT ARRANGEMENT

The invention relates to a polar loop circuit arrangement (1), for the generation and amplification of amplitude and phase modulated signals (f A), comprising at least: a power amplifier (4), an amplitude and a phase-lock loop (1.1, 1.2). A signal modulation is carried out by means of the amplitude...
