5.1.3. Reference Design of RF Antenna Interface
Areference design of mainantenna padis shown as below. A π-type matching circuit should be
reservedfor better RF performance, and the π-type matching components (R1/C1/C2) should be placed
as close to the antenna as possible. The capacitors are not mounted by default.

5.1.4. Reference Design of RF Layout
For user’s PCB, the characteristic impedance of all RF traces should be
controlled as 50Ω. The impedance of the RF traces is usually determined by
