Introduction
Why a power amplifier is important?
Power amplifier is a key element to build a wireless communication system successfully.
There is a trade-off between power per cost vs. efficiency and linearity.
Digital communications require more peak power for the same bit error rate.
To minimize spectral re-growth and interferences, transmitters have to be more linear.
Clear modulation scheme requires more higher power and broader bandwidth.
