Abstract:
(EN) This power amplification circuit is provided with: a band division unit (11) which generates N band signals (X1-XN) from a transmission signal (BS); N distortion compensation units (121-12N) which generate N distortion compensation signals (Y1-YN) by subtracting a feedback signal (FS) from the band signals (X1-XN); a combining unit (14) which generates a combined signal (CS) by combining the distortion compensation signals (Y1-YN); a power amplification unit (15) which amplifies the power of the combined signal (CS); a branch unit (16) which causes a part of an output signal of the power amplification unit (15) to branch off; and an attenuation unit (17) which generates the feedback signal (FS) by attenuating the power of the part caused to branch off by the branch unit (16).
(FR) L'invention concerne un circuit d'amplification de puissance comprenant : une unité de division de bande (11) qui génère N signaux de bande (X1-XN) à partir d'un signal de transmission (BS) ; N unités de compensation de distorsion (121-12N) qui génèrent N signaux de compensation de distorsion (Y1-YN) par soustraction d'un signal de rétroaction (FS) des signaux de bande (X1-XN) ; une unité de combinaison (14) qui génère un signal combiné (CS) en combinant les signaux de compensation de distorsion (Y1-YN) ; une unité d'amplification de puissance (15) qui amplifie la puissance du signal combiné (CS) ; une unité de dérivation (16) qui dérive une partie d'un signal de sortie de l'unité d'amplification de puissance (15) ; et une unité d'atténuation (17) qui génère le signal de rétroaction (FS) en atténuant la puissance de la partie dérivée par l'unité de dérivation (16).
(JA) 電力増幅回路は、送信信号(BS)からN個の帯域信号(X~X)を生成する帯域分割部(11)と、帯域信号(X~X)からフィードバック信号(FS)を減算してN個の歪み補償信号(Y~Y)を生成するN個の歪み補償部(12~12)と、歪み補償信号(Y~Y)を合成して合成信号(CS)を生成する合成部(14)と、合成信号(CS)の電力を増幅する電力増幅部(15)と、電力増幅部(15)の出力信号の一部を分岐させる分岐部(16)と、分岐部(16)で分岐された当該一部の電力を減衰させてフィードバック信号(FS)を生成する減衰部(17)とを備える。
