ABSTRACT
This derivation looks at class A amplifier electrical performance versus power based on a minimal parameter set. This allows an engineer to make accurate performance predictions (the results of this derivation are not intended to replace simulation) without having to actually execute a design. Additionally, the results can be used to great advantage in estimating system performance. Much of the derivation is based on compression characteristics, making it a unique approach to analyzing power amplifier performance. A fast and easy to use engineering tool can be created by programming the results into an Excel spreadsheet.
