pa hf

Hi,
I'm looking for a simple way (formulas or software) to calculate pi filters in a final (PA-HF) to operate in a given frequency and in general how to calculate final power amplifier.

www.hfpower.com

It is ACOM amplifiers manufacturer. This AMPS have the best auto-adjustable antenna tunner /PI filter/

You can ask them for more information.
The people are so responsible and obliging
