4.3.1 Supported Antenna Configuration

Table 4-1 describes the supported antenna mode configurations.

Table 4-1 Antenna Mode Supported Configuration
Antenna Mode TX RX
Chain 1 Chain 2 Chain 1 Chain 2
5-GHz SISO X A Band X A Band
2.4-GHz SISO X BG2 X BG2
2.4-GHz MIMO BG1 + BG2 BG1 + BG2 BG1 + BG2 BG1 + BG2

RF_ANT1 is the main antenna for 2.4-GHz SISO and the default antenna for the 5 GHz on the WL1837 and WL1807 modules.

RF_ANT2 is a MIMO-only (MCS8 to MCS15) secondary antenna for 2.4-GHz MIMO operation and can be a diversity antenna for the 5 GHz on the WL1837 and WL1807 modules.

Figure 4-8 shows an example of the antenna connection that covers all antenna mode configurations.
