The class of the power amplifier (or linearity) depends by the modulation of the amplified signal.
In general a pure Class A amplifier is avoided in power amplification, due to its very low efficiency. Class AB is the most used power class.
What is the modulation ?
What are the permitted harmonic levels ? (H2, H3 etc)
What kind of supply will you use ? (Battery, Transformer, Switchmode etc)
What kind of circuit technique you intend to use ? (SMD, lumped, distributed,MMIC etc.)
What is the thermal constraints ?
What is the screening specification ?
