Özet

The main purpose of this study is to find a relation between power amplifier (PA) circuit component values and delay terms of the PA model polynomial by using measurement results. A PA designer can use this relation to determine component values while designing memoryless/linear PAs. For this purpose, a behavioral model with memory is worked on; the model, modeling approach, experimental set-up and results are presented. Memory depths are determined for a 1-2GHz 10W Class AB power amplifier with parametric results. The advantages of the elaborated model are presented. Relations between the bias circuit components and the memory terms are investigated.
