FIELD: physics; radio.
SUBSTANCE: invention can be used in radio engineering and communications. The amplifier has first (1) and second (3) output transistors, a two-terminal circuit (5) for local negative feedback, symmetrical load circuit (6), first (9) blocking capacitor, first (11) and second (12) current-stabilising two-terminal circuits, second blocking capacitor (13), first (14) and second (15) complementary transistors, complementary two-terminal circuit (16) for negative feedback.
EFFECT: increased suppression ratio of control signal in a wide frequency range.
