Could you clarify the bandwidth ranges (minimum value and step size) of the controlled analog low pass filters and the programmable FIR digital filters (up to 80taps) in TX and RX I/Q paths of the ADRV9026? Also how the FIR fillers will be controlled in the SW GUI?
Sorry missed responding to this one.
The filter response depends on the Profile (Use case selected). IN GUI once you select a profile you can go to the Tx and Rx tabs , you can see the filter response for that profile. Attached below one sample response FYR.
You can zoom in to see the response in more details. The dark blue is the analog filter response, the black one FIR and the blue composite response.
It will be great if you could also add the BW (max, min) for the rest of the filters in the Tx/Rx paths.
The coefficients of each digital filter are available in UG-1727, Please refer to the DIGITAL FILTER CONFIGURATION for more details.
You can use tools like Matlab to plot the frequency response.
