A Novel N-way Distributed Doherty Amplifier with Improved Efficiency at High PAR Signals

A novel three-way distributed Doherty power amplifier, with improved efficiency at high peak-to-average ratio (PAR) signals such as W-CDMA and OFDM, is presented. This distributed Doherty amplifier consists of one main amplifier and two peaking amplifi...
In modern digital wireless communication systems, such as IS-95, PCS, W-CDMA, OFDM and so on, power amplifiers have progressed towards having a wide bandwidth and a large number of carriers. Recently, orthogonal frequency division multiplexing (OFDM) modulation has become an attractive technique for transmitting information efficiently within a limited...
