Rob, I'd like to try this circuit as the mixer for a direct conversion receiver. I also have some 12…

thanks a million I seen the schematic but with the dots on it wasnt sure of the resistor values thanks…

There is a schematic at the top of the page that has the part values on it. The 2 grounds…

Its a common library found on the web. I think AD7C was the first to bring one out. Google him,…
