Different classes of RF power amplifiers with respect to their efficiencies are also discussed, as well as different linearisation techniques presently in use and those at the research and developmental stage. This paper illustrates with examples how more efficient modulation schemes and more efficient classes of RF power amplifiers can be adopted for use in data communications, if the inherent problem of spectral spreading ,which results from non-linear output of RF power amplifiers at the front end of devices can be effectively handled.
