Abstract
A power amplifier arrangement () for amplifying an input signal to produce an output signal comprises a plurality N of amplifier sections (), a first input transmission line () comprising multiple segments and a first output transmission line () comprising multiple segments. Each amplifier section comprises one or more first transistors (T) distributed along the first input transmission line () and the first output transmission line (). Each amplifier section is configured to amplify a portion of the input signal to produce a portion of the output signal. A portion of the input signal is one of N portions of the input signal partitioned on any one or a combination of an amplitude basis and a time basis. The output signal is produced at an end of the first output transmission line () by building up N potions of the output signal from each amplifier section.
