An amplifier circuit comprises a first amplifier (11). The output of the first amplifier (11) is coupled to an output node (15) via a first transmission line (13) comprising a first portion (13i) and a second portion (132). An output of a second amplifier (21) is coupled to the output node (15) via a second transmission line (23) comprising a first portion (23i) and a second portion (232). Tn e output of an auxiliary amplifier (30) is coupled via an auxiliary transmission line network (33i, 332; 334, 335, 33Q) to a first intersection between the first and second portions (13χ, 132) of the first transmission line (13), and to a second intersection between the first and second portions (23i, 232) of the second transmission line (23). |
