uBITX40 filtered


Dear all,

I'm thinking about the adding low pass filters to the output of all
oscillators. The goal is to filter the square wave of the clock generator. I came up with this mixer solution. Using a JFET mixer is just my other experiment.

Question is if this circuit would clean the output signal?

Also, I'm thinking about modifying the IF amplifiers to be tuned.

Any ideas?
