Hi,
We used the EVAL-ADMV4420 to verify the ADMV4420, we use the same parameters as user guide of ADMV4420-EVALZ (RF = 18GHz at -40dBm, LO = 17GHz, 50MHz on-board Crystal). But we found that the IF-out FFT waveform is different from the results in the user guide (Please refer to the photos below). there are other signals at 1.0135GHz.
Below is our test environment, we want to know what factors will cause additional signals in IF-out? Could you give us some suggestions?
Have a nice day
Klex
