The amplifier arrangement comprises a first cascade of quarter wavelength transmission line segments coupled to receive a first set of amplifier stages, and at least a second cascade of quarter wavelength transmission line segments coupled to receive a second set of amplifier stages. The first cascade and second cascade are connected to a common node, for example in parallel to an output node, or in parallel to an intermediate node.
