3
RF_N
I/O
Differential (with RF_P) receiver input/transmitter output
4
VDD_RF
Power
1.8V RF supply (LNA and PA); should be connected to VREG_OUT
5
RF_TX_ALT_P
O
Differential (with RF_TX_ALT_N) transmitter output (optional)
6
RF_TX_ALT_N
O
Differential (with RF_TX_ALT_P) transmitter output (optional)
7
VDD_IF
Power
1.8V IF supply (mixers and filters); should be connected to VREG_OUT
