Abstract
This paper describes the architecture and performance of a demonstrator for a wideband multi-carrier power amplifier for use as a powerbank in shipboard HF communications. The demonstrator was built and evaluated to prove an advanced concept comprising two nested feedforward linearizers for suppressing unwanted emissions associated with intermodulation and harmonic distortion.
