Re: Current limit for PA

Hi Marco!

Once you have everything adjusted I don't think you will need current protection anymore, except for cases when your antenna fails.

If you start operating at 12V you will be able to save your PA FET until you tune the antenna.

After the antenna tuner is adjusted you can switch the voltage at PA input for higher power.

My proposal was for the bench/desk setup and tuning, when it is much more likely to kill the FET.
