Hello.

I have a problem with the signal distortion after quadrature demodulator (AD8333).

After AD8331 -> signal without distortion.

My hardware configuration:

Below shows the waveforms after the mixer (P2 Jack).

CH1 -  I1NO

CH2 -  I1PO

1)  P1 = -30 dBm

2) P1 = -20  dBm

3) P1 = 0  dBm

Where there may be a problem ?

I hope to see a sinusoidal waveform.

I am hope for your help.

Thanks.
