4.1.3. Reference Design of RF Antenna Interface

A reference design of ANT_MAIN and ANT_DRX antenna interface is shown below. It should reserve a
π-type matching circuit for better RF performance. The capacitors are not mounted by default.
NOTES
1. Keep a proper distance between the main and the Rx-diversity antenna to improve the receiving
sensitivity.
Place the π-type matching components (R1/C1/C2 and R2/C3/C4) as close to the antenna as
