Freescale Semiconductor introduces the Doherty amplifier, which has many characteristics that enable high efficiency. When properly designed, it can deliver efficiency increases of 11 to 14% when compared to standard parallel Class AB amplifiers that are traditionally utilized in wireless base station transmitters. A Doherty amplifier consists of two amplifiers--carrier and peaking-operating under vastly different conditions. The RF power transistors in Doherty amplifiers must provide good output impedance matching under both linear ...
