Title (EN) POLAR TRANSMITTER FOR CORRECTING PHASE AND AMPLITUDE BY SELECTIVELY USING MULTI-LOOP
(FR) ÉMETTEUR POLAIRE PERMETTANT DE CORRIGER UNE PHASE ET UNE AMPLITUDE EN UTILISANT SÉLECTIVEMENT UNE MULTIBOUCLE
(KO) 다중 루프를 선택 이용하여 위상과 진폭을 보정하는 폴러송신기
Abstract: front page image
(EN)The present invention relates to a polar transmitter which comprises a phase modulator, an up-converter, and a feedback loop having a power amplifier included in a feedback path. The polar transmitter comprises a comparator which compares a first output signal of the phase modulator, a second output signal of the up-converter and a third output signal of the power amplifier with an output signal of a polar converter, and provides the output signals as correction signals for correcting the output signal of the polar converter.
(FR)La présente invention concerne un émetteur polaire qui comprend un modulateur de phase, un convertisseur-élévateur de fréquence, et une boucle de rétroaction ayant un amplificateur de puissance inclus dans un chemin de rétroaction. L'émetteur polaire comprend un comparateur qui compare un premier signal de sortie du modulateur de phase, un deuxième signal de sortie du convertisseur-élévateur de fréquence et un troisième signal de sortie de l'amplificateur de puissance avec un signal de sortie d'un convertisseur polaire, et fournit les signaux de sortie comme des signaux de correction permettant de corriger le signal de sortie du convertisseur polaire.
(KO)본 발명은 위상변조기, 상향변환기, 및 전력증폭기가 피드백 경로에 포함되는 피드백 루프를 포함하는 폴러송신기에 관한 것이다. 이 폴러송신기는, 위상변조기의 제1 출력신호, 상기 상향변환기의 제2 출력신호, 및 상기 전력증폭기의 제3 출력신호를 폴러변환기의 출력신호와 비교하여, 상기 폴러변환기의 출력신호를 보정하기 위한 보정신호로서 제공하는 비교기를 포함한다.
