6.1.2. Reference Design for Main and Rx-diversity Antenna Interfaces

A reference circuit design for main and Rx-diversity antenna interfaces is shown below. Reserve a π-type
matching circuit for each antenna to achieve better RF performance, and place the π-type matching
components (R1/C1/C2, R2/C3/C4) as close to the antennas as possible. The capacitors are not
mounted by default and the resistors are 0 Ω.
