         RAK831 provide three types of RF interface like SMA and other two IPEX connector.See the 

image as below for TDD_TXRX

、TX_DEV、RX_DEV. Consider the developer may require to support 

Tx/Rx simultaneously,therefore to make the compatible design. The Tx_DEV  is the  Tx channel, need 

change the C224 to NC and C216 with CAP(56pf/0402) or 0ohm resistance when using as standalone 

channel.RX_DEV is the Rx channel, need change C240 to NC and C244 with CAP(56pF/0402) or 

0ohm resusrance. The default design select the Path to TDD_TXRX via RF switch and using external 

antenna.
