Abstract
This chapter discusses basic power amplifier (PA) design parameters along with high-efficiency PA designs based on switch-mode operation and harmonic terminations. In addition, continuum of some classes of operation is also discussed for bandwidth enhancement in PAs. In order to develop basic understanding of Doherty PA and Chireix outphasing PA, a brief discussion on their architecture is also presented in this chapter. This chapter also introduces various linearization schemes which will be further discussed in detail for broadband applications in the later chapters. A basic architecture of delta-sigma modulation (DSM)-based transmitter is also presented which will be comprehensively discussed in later chapters for wireless transmission applications.
