An amplifier arrangement comprises N amplifier stages 101 to 10N, wherein N is an integer equal or greater than five. The amplifier arrangement comprises a cascade of quarter wavelength transmission line segments 111 to 11M coupled between an output of an amplifier of a first amplifier stage and an output node 15 of the amplifier arrangement. At least one intermediate junction 12 in the cascade of quarter wavelength transmission line segments comprises: a first amplifier coupled directly to the intermediate junction 12; and a second amplifier coupled to the same intermediate junction 12 via a connecting quarter wavelength trans mission line 131.
