6.1.1. Main and Rx-diversity Antenna Interfaces Reference Design
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 resistors are 0
Ω
.
