Antenna Diversity Utility#

RAIL Antenna Diversity Utility#

This optional software component can be enabled to include default functionality related to antenna diversity configuration.

When using a Silicon Labs-developed board, the configuration options for this software component are set up automatically based on the selected board. When using a custom board, manually configure the configuration options.

Configuration Options#

The following configuration options can be changed:

  • Antenna Diversity:

    • RX Antenna Diversity Mode: Choose the mode to use for receive antenna diversity. The possible modes are disabled, enabled, Antenna 0 only, or Antenna 1 only.

    • TX Antenna Diversity Mode: Choose the mode to use for transmit antenna diversity. The possible modes are disabled, enabled, Antenna 0 only, or Antenna 1 only.

    • Enable/disable Runtime PHY Selection: This option only works when using the Silicon Labs Zigbee or Open Thread stacks. If enabled it will allow turning on and off the antenna diversity version of the IEEE 802.15.4 PHY at runtime by these stacks.

The following hardware options can be changed:

  • Configure the antenna diversity transmit select GPIO (ANT0 signal).

  • Configure the antenna diversity inverse transmit select GPIO (ANT1 signal).
