Figure 35: Antenna matching circuit (MAIN_ANT)
In above figure, the components R1, C1, C2 and R2 are used for antenna matching, the values of
components can only be achieved after the antenna tuning and usually provided by antenna vendor. By
default, the R1, R2 are 0Ω resistors, and the C1, C2 are reserved for tuning. The component D1 is a TVS
for ESD protection, and it is optional for users according to application environment.
The RF test connector is used for the conducted RF performance test, and should be placed as close as to
the MODULE’s MAIN_ANT pin. The traces impedance between MODULE and antenna must be controlled
in 50Ω.
Figure 36: Antenna matching circuit (AUX_ANT)
In above figure, R3, C3, C4 and R4 are used for auxiliary antenna matching. By default, the R3, R4 are
0Ωresistors, and the C3, C4 are reserved for tuning. D2 is a TVS for ESD protection, and it is optional for
users according to application environment.
Two TVS are recommended in the table below.
