receive side, the RX antenna is ac-coupled to the differential RFIN inputs and these capacitors along with
inductor L1 form a matching network. Inductors L2 and L3 are ac-coupled to ground to form a frequency
trap. For the transmit side, the TX antenna is connected to the differential PAO outputs, and inductors L4
and L5 provide DC-biasing to VDDA but are ac-isolated. CT_Bias is not required or used.
