There are a number of methods of producing linear efficient amplifiers that are currently receiving a great deal of attention within the power amplifier research community. As the bandwidths of signals has risen to up to 20MHz per channel and signals required to be amplified now have peak to average power ratios of greater than 10dB, this has led to the need for new approaches to amplifier linearisation. This talk will describe the latest research into two promising techniques of efficient amplifier linearisation, the Inverse Doherty amplifier and the Non-linear Envelope tracking technique. These techniques are capable of amplifying 4th generation signals with efficiencies of greater than 50%.
