5.1.3. Reference Design of RF Antenna Interface
A reference design of main antenna pad 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) should be placed as close
to the antenna as possible. The capacitors are not mounted by default.
