The European Union has established the TARGET network of excellence (NoE) to focus on microwave power amplifier (PA) technology research. It aims to integrate the research resources comprised of many research groups covering the full range of expertise in PA technology. TARGET'S linearisation expertise covers leading edge researchers in classical and new linearisation techniques, including feedforward, predistortion, feedback and envelope elimination and restoration (EER), adaptive and non-adaptive, digital and analog, baseband, IF and RF, together with device, circuit and system modeling and behavioural analysis techniques. This paper reviews key linearisation issues to be faced in evolving linearisation solutions for future complex PA systems destined for a wide range of advanced wireless systems.
