Hi, My ADI friends:
As we know there are LNA+Mixer+TIA+LPF in the RX chain;
And there are RX QEC / RFDC offseet / BBDC offset calibrations for RX channel.
My understanding for when to do BBDC cal /RFDC cal as below table:
My question is :
1. If just LMT gain changed & LFP gain not changes, We just need to do RFDC cal only&No need BBDC cal?
2. If LMT gain not changed & just LFP gain changes, We just need to do BBDC cal only&No need RFDC cal?
3. If both LMT gain & LPF gain changes, We just need to do both BBDC cal & RFDC cal together?
