Is This Radio Frequency Mixer the Game Changer We've Been Waiting For?

Well thank you so much! Such a nice comment. RJ

Used this device for a DC RX. It worked well at the factory bias. However, now that I know this, I would like to see what it could do with a bit more gain. Thanks!

Well keep watching as I will show you shortly. RJ

I've only used hot tweezers for removal and a small tip or hot air for swapping.

They work both ways as you saw. Sometimes they want to attract the part. But the good is you are not heating other things and it is fast. RJ

Hi RJ, that was very interesting. Just a silly question (Mr Jordan is in shock) instead of soldering in different resistors wouldn't a temporary potentiometer been able to be use for testing instead? I believe that I am correct in saying that the db scale is logarithmic and not linear. So increasing by 17 db is a lot more than a person not familiar would think (like me). Curious to see what the next step in the process takes us. Take care Rick

Rick, Thanks for the input it’s good to hear from you again. That would be great except for two issues. One is the size of pads I was working with. Under the microscope they may look ok but those 603 pads are a little small to solder wires onto without pulling the pads off. Also I would be adjusting some what blind as I would be able to measure while testing and adjusting. So using fixed 1% resistors worked better I think in this case. As you could see it wasn’t that hard to change them. RJ
