Chapter 12. Power Amplifiers
Power amplifiers are the most power-hungry building block of RF transceivers and pose difficult design challenges. In the past ten years, the design of PAs has evolved considerably, drawing upon relatively complex transmitter architectures to improve the trade-off between linearity and efficiency. This chapter describes the analysis and design of PAs with particular attention to the limitations that they impose on the transmitter chain. A thorough treatment of PAs would require a book of its own, but our objective here is to lay the foundation. The reader is referred to [1, 2] for further details. The chapter outline is shown below.
12.1 General Considerations
As the first step in our study, we consider a transmitter ...
