Love the strategy that you are using, it 's quite clever. Thx for the great explanation. You covered the design well. I also thought the breadboard using sticky copper foil also a great way to build this mixer. Again, thx for taking the time in sharing your clever mixer design.

Thanks! I first saw this design in projects from S53MV.

Mindblowing circuit, fantastic explanation. Really quite clever.

[@AllElectronicsChannel]

Thank you!!

Need a lab tour !!

[@archerkee9761]

this is amazing! very good explainer!

[@AllElectronicsChannel]

Thank you!! Welcome to the channel

[@SandeepKumar-jj7zi]

Nice. What are the rf diodes you used in this?

[@AllElectronicsChannel]

I like BAT15-099

[@rjordans]

Nice one again, thanks! Regarding the stubs, the quarter wavelength long is clear, but does their width have much impact?

[@AllElectronicsChannel]

The width will change the impedance of the stub!! To get a deeper notch you use a larger width, so the impedance is lower than the 50ohm line

[@rjordans]

@@AllElectronicsChannel thanks for the quick response. Is this just the attenuation here or does this also impact the Q?

[@AllElectronicsChannel]

It changes the Q also! Larger stub will have wider notch

[@rjordans]

Thanks, sounds like this will take some experiments to really get a good idea on

[@AllElectronicsChannel]

Yep!! Go go go!!

[@footstoolofgodflatearth2933]

what is the 1 Mhz used for? why are you using 1Mhz to modulate the 2Ghz?

[@maazkhan4824]

I love it thanks

[@AllElectronicsChannel]

I'm glad

[@PeterB396]

Inspiring 😁

[@PastoriciciRobertYO4HFU]

Your explanation is not accurate. The output RF is not LOx2, is (LOx2) +/-IF. You will be able to see it by reducing the span and BW of spectrum analyzer due to small value of 1MHz.

Probably a misspelling
