The present manuscript details a wideband high power amplifier design, based on a 5-mm GaN power bar. In particular, a broadband input large-signal matching condition has been realized, that ensures optimal power transfer under actual device operation. The measured performance of the PA perfectly matches the expected predictions based on large-signal measurements carried out on a 1.25-mm GaN elementary cell
