Thanks DM5RM,

I've got it all wrong. I've thought that the output is SMP and the input is MCX.

Apparently they are more exotic

Hi DB8TF,

Great work!

Could you please share what are the changes you have done to the board?

I own the same PA unit, however I’m trying to figure out what changes need to be done.

I see that you have replaced the input connector with SMA (BTW, what is the original connector?)

And that the circulator was replaced with a N-type. There are few copper patches (I assume for better matching). What changes are not so obvious? Is the amplifier still working as a Doherty one?

thanks

Yoram
