3.4 Layout version improving TX to RX isolation
The isolation between the TX port and the RX port on the standard evaluation board is typically about 25 dB.
This isolation can be improved to 35 dB by adding a grounded length of line at the ground pins next to the TX
output pin, as shown in Figure 16. Details of the used compensation structures can be found in Figure 17.
