[ARC5] HF Converter - feeding mixer with a square wave?

[Bob kb8tq]

Hi

With just about any mixer circuit you can reasonably come up with, 
driving with a square wave vs driving with a sine wave is not a big
deal. Responses at N times the LO are just part of the process. You
*might* see another couple db at odd multiples using a square wave.
Then again, you might not. Either way, the response is there. 

This is one of the reasons why you tend to put some filtering in front 
of the mixer …..
