DPD and Sniffer are both needed in our application.
They are sharing ORX paths by switching connections to Tx and Sniffer antenna.
The config is: TxLO = RxLO = RF LO1, ORX1 LO= AUX LO.
We have to config ORX LO to AuxLo because we need to sniffer different band whose frequency could be far away from TX frequency.
But this brings DPD track failures even if we config ORX AuxLO to same frequency with TxLO.
(DPD Error code: 0x341D "DPDTrack: DPD stability error occurs". Direct/Inrect EVM: 85%)
It seems AuxLO cannot work for function of DPD tracking.
Question:
1. Could you confirm if the issue i mentioned is expected?
2. As for the DPD & Sniffer requirement, how can we configure the clocks so that both of them can work normally?
(We hope there is API to switch AUX LO/TX LO for ORX path during runtime, but it seems impossible? )
3. If AuxLO cannot work for DPD track, can we export DPD model when it works and load it during DPD initialization and do not execute DPD track.
Is it possible that ACPR is still improved like we are doing DPD track?
Thanks.
