I have been trying to simulate a few classes of power amplifiers such as
- Class A
- Class AB
- Class B
- Class E
- Class F
I have developed the models for the classes using Advanced design system (ADS) Keysight software for RF design.
However, I am confused about how to simulate the spectral of the power amplifier at certain carrier frequencies such as 2 GHz and a bandwidth of 5 MHz.
I would like to seek your kind help with how the simulation of the spectral can be achieved. I have conducted Single Tone and Two-Tone Simulations for the models with this point in doubt.
Thank you in advance.
Dear Mena
you need to model the HPA using some mathematics models such as the Volterra series or Saleh model,... etc. also you need to train these models to fit your actual data set from an actual amplifier
after that, you can use exist formula to calculate any criteria
Dear Mohannad,
Thank you for your kind answer.
I already have developed the amplifier circuit on ADS and my only question is if there is a method to achieve the ACPR and simulate the power spectrum from the given schematic.
