Power amplifier is a key element to build a wireless communication system successfully.0 y) _8 h. n- c6 i
There is a trade-off between power per cost vs. efficiency and linearity. 4 @; O" F y2 y: ]1 B5 R( ODigital communications require more peak power for the same bit error rate.) I, O# a, R% z5 l
To minimize spectral re-growth and inteRFerences, transmitters have to be more linear.7 V0 N7 y) @# W6 z- d% ^
Clear modulation scheme requires more higher power and broader bandwidth. + `0 \# D( h' F4 RWhat is a solution from Ansoft?
