Hello,
I require -55dBc spurious suppression for a dual tone signal, separated by 20Mhz.
For LMS6002 i have measured ~-50dBc for TX and -40dbC for RX. Here is a measurement for TX:
It is impossible to further reduce I/Q imbalance spurs, because two tones require different compensation values. So it seems that LMS6002 does not fit my needs.
I am interested about LMS7002 performance regarding this matter. Has anyone tested this before? Datasheet promises -55dbc max, but what are the real life numbers?
Thank you!
