Title (EN) HARMONIC INJECTION PUSH-PULL AMPLIFIER
(FR) AMPLIFICATEUR SYMÉTRIQUE À INJECTION D’HARMONIQUE
(JA) 高調波注入プッシュプル増幅器
Abstract: front page image
(EN)In a harmonic injection push-pull amplifier, a push-pull amplifier circuit (5) comprises balance/unbalance conversion circuits (3, 4) and two unit amplifiers (1, 2) connected to the balance/unbalance conversion circuits (3, 4) and operating in reverse phase to each other, and receives a fundamental signal. The push-pull amplifier circuit (5) is equipped with a harmonic distortion amplifier generation circuit that inputs a harmonic distortion signal including an odd-order harmonic distortion signal of the fundamental signal to each of the two unit amplifier (1, 2) from the input side thereof. Consequently, the odd-order harmonic distortion signal is input together with the fundamental signal, thereby reducing the distortion.
(FR)L’invention concerne un amplificateur symétrique à injection d’harmonique. Un circuit d’amplificateur symétrique (5) comprend des circuits de conversion d’équilibre/déséquilibre (3, 4) et deux amplificateurs (1, 2) raccordés aux circuits de conversion d’équilibre/déséquilibre (3, 4) et fonctionnant en phase inversée l’un par rapport à l’autre, et reçoit un signal fondamental. Le circuit d’amplificateur symétrique (5) est équipé d’un circuit de génération d’amplificateur de distorsion d’harmonique qui transmet un signal de distorsion d’harmonique comprenant un signal de distorsion d’harmonique d’ordre impair du signal fondamental à chacun des deux amplificateurs (1, 2) depuis la face d’entrée de ceux-ci. En conséquence, le signal de distorsion d’ordre impair est entré conjointement au signal fondamental, réduisant ainsi la distorsion.
(JA) 高調波注入プッシュプル増幅器に関し、平衡/不平衡変換回路3,4と、その平衡/不平衡変換回路3,4と接続され互いに逆相動作する2つの単位増幅器1,2とを有し、基本信号が入力されるプッシュプル増幅回路5において、2つの単位増幅器1,2のそれぞれに入力側から基本信号の奇数次高調波歪信号を含む高調波歪信号を入力する高調波歪信号発生回路を備え、基本信号と共に奇数次高調波歪信号を入力することにより低歪化を図るようにしたものである。
