Why a power amplifier is important? 0 v0 a& u2 d7 l) F1 wPower amplifier is a key element to build a wireless communication system successfully. 5 v$ E1 D* I9 S2 A; N9 s! s2 VThere is a trade-off between power per cost vs. efficiency and linearity. $ `* ~9 ?* g! s& r- D& O$ I- \Digital communications require more peak power for the same bit error rate. # Y1 m% S2 c; `. a; v) U.
