4.1.3. Reference Design of RF Antenna Interfaces
A reference design of main and Rx-diversity antenna interfaces is shown as below. It is recommended to reserve a
π-type matching circuit for better RF performance, and the π-type matching components (R1/C1/C2 and R2/C3/C4)
should be placed as close to the antennas as possible. The capacitors are not mounted by default.
