Amplifier structure

An amplifier structure comprising a transistor element having a plurality of sub-sections arranged adjacent to one another along a transistor element axis, a bias distribution element comprising a first part and a second part, the first part configured to receive a bias signal and the second part configured to supply the bias signal to each of the sub-sections of the transistor stage, wherein the first part is configured and arranged to deliver the bias signal to a distribution point and the second part is configured to diverge from the distribution point to provide the bias signal to each of the sub-sections of the transistor element, the distribution point arranged substantially facing a centre point of the transistor element axis.
