Introduction
The gain table controls the RF output power of the ATWINC3400A device. This application note describes the Wi-Fi® and Bluetooth Low Energy gain table structure and procedure to derive the Wi-Fi and Bluetooth Low Energy gain tables during the product development phase.
Perform the following steps to derive the Wi-Fi and Bluetooth Low Energy Application Gain Table:
- Performance Gain Table: Verify the Digital Gain (DG) setting to meet IEEE 802.11 and Bluetooth specifications.
- Certification Gain Table: Adjust the DG setting for the specific regulatory region compliance.
- Application Gain Table: Combine step 1 and step 2 to produce a composite gain table, referred to as an "Application Gain Table", which can be used in the firmware for the product.
