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

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