High efficiency is a crucial design consideration. This is true not only for power amplifiers (PAs), but also for transmitters such as the Doherty PA and the supply-modulated PA, due to thermal management, reliability, and size [1]-[3] issues. Severa

A power amplifier (PA) for a femto-cell base station should be highly efficient, linear and small. The efficiency for amplification of a high peak-to-average power ratio (PAPR) signal was improved by designing an asymmetric Doherty PA (DPA). The line

The effect of the peaking offset line on the Doherty amplifier operation is investigated. The peaking amplifier of the Doherty structure operates at a C-bias condition for the load modulation. With the C-bias, the amplifier has a poor AM-PM character
