2.1 Wi-Fi Gain Table Format

The format of the Wi-Fi gain table displays below. This table needs to be filled with DG, PA and PPA values, which are unique for a given Wi-Fi channel and data rate. Microchip recommends using the default gain table and editing the gain values based on the user requirement. The default gain table can be accessed from the location mentioned in Section 7 (Gain Values Download) of the ATWINC15x0/ATWINC3400 − Integrated Serial Flash and Memory Download Procedure Application Note (DS00002378).

Note: The PPA and PA have a similar table to the DG gain table, but the values of PPA and PA gains are fixed at 15 and 18, respectively, for all channels and data rates.

The following table format is an example for the DG table.

The following figure is an example of the sample DG gain table.

The first row represents the Wi-Fi channel number and the first column represents the data rate. The Digital Gain (DG) value has to be determined by the user for all of the combinations of the Wi-Fi channel number and data rate.

The following table format is an example for the PA and PPA gain table.

Note: Microchip recommends following the gain table template as it is in the WINC3400 Firmware Upgrade Project. If upgrading to the newer version of the firmware, use the gain table template from the latest firmware version package to update the gain table with the required DG values.
