Hello everyone,
I have the following issue,
I am using a mixer in order to rectify the sine signal. But, the output is not rectified. In fact, it is just flipping (or just changing polarity).
I have the following configuration:
Mixer Input frequency: 50Khz
Mixer local oscillator input (LO): 50Khz coming from PWM.
Reference : Vdda/2
Both signals are in phase, components are started correctly.
I don't really understand where the error lies.
Looking forward for your suggestions.
Regards
Awais

This mixer is working just as it should. When you apply two of the same frequencies to a mixer there is two outputs one is Upper Sideband and lower Sideband and Image frequency in this case 0 as the two signals are the same frequency.

Why would a mixer rectify a signal ?
Please let us know what is mixed with what, what do you expect as result and what is the observed result ?

Thank you for your reply.
I am trying to implement the following application note (see attachment).
and I am getting the result in the picture attached (Yellow wave is the input entering into the mixer and purple is the mixer output).
Looking forward for your suggestions.

Here is the configuration settings for the mixer component. As you can see I set the LO and the input to the same frequency and it warns that the output is a DC level of 0.
