The present disclosure relates to an amplifier arrangement (1, 100, 200) comprising a first amplifier device (2, 102, 202) and a second amplifier device (3, 103, 203) where each amplifier device (2, 3; 102, 103; 202, 203) is connected to an input circuit (8, 108) and has a first type output terminal (4, 6; D) and a second type output terminal (5, 7; S), where the output terminals (4, 6, D; 5, 7, S) are connected to an output circuit (9, 109, 109′). The first type output terminal (4, D) of the first amplifier device (2, 102, 202) is connected to the second type output terminal (7, S) of the second amplifier device (3, 103, 203) by means of a first connection (10, 110), and the first type output terminal (6, D) of the second amplifier device (3, 103, 203) is connected to the second type output terminal (5, S) of the first amplifier device (2, 102, 202) by means of a second connection (11, 111). The first type output terminal (4, D) of the first amplifier device (2, 102, 202) and the first type output terminal (6, D) of the second amplifier device (3, 103, 203) are electrically separated in the output circuit (9, 109, 109′), and the second type output terminal (5, S) of the first amplifier device (2, 102, 202) second type output terminal (7, S) of the second amplifier device (3, 103, 203) are electrically separated in the output circuit (9, 109, 109′).
