We are developing Sniffer function with ADRV9029.
The Sniffer signal is received by ORX path which is shared with DPD ORX, multiplexing controlled by an external switch.
The RX/TXs are using LO1, while ORX is using Auxiliary LO for Sniffer signal reception.
However, we see that, when Rx/Tx is working under N77 Band(e.g., 3.35GHz), we cannot configure ORX LO(Aux LO) to frequency of N79(e.g., 4.85GHz) since there is error reproted.
We tried to configure some other frequencies for Aux LO and see that only when the difference between RF LO and Aux LO is within 700MHz, there is no error reported.
So, could you please tell us what's the restriction in Aux LO configuration?
What can we do if we need to sniffer some frequencies that are far from RF requency working band?
Thanks!
