1. A power amplifier arrangement for amplifying an input signal to produce an output signal comprising:

  • a plurality N of successive amplifier sections, wherein N=2, 3, or more;

    a first input transmission line comprising multiple segments; and

    a first output transmission line comprising multiple segments;

    whereineach amplifier section comprises one or more first transistors distributed along the first input transmission line and the first output transmission line such that gates of the one or more first transistors are connected to respective segments of the first input transmission line, drains of the one or more first transistors are connected to respective segments of the first output transmission line; and

    whereineach amplifier section is configured to amplify a portion of the input signal to produce a portion of the output signal, and whereina portion of the input signal is one of N portions of the input signal partitioned on an amplitude basis, andthe output signal is produced at an end of the first output transmission line by building up N portions of the output signal from each amplifier section.
