Abstract
A solid-state power amplifier (SSP A) linearisation technique based on the analogue implementation of the LMS algorithm is here presented. This technique leads to a linearisation scheme next to an hyperstable adaptive system, thus being suitable for the compensation of SSPA parameter variations. The lineariser is experimented on a class-A power amplifier backed-off by 3 dB.
