Z1 and Z3 can be used for additional tuning for external antenna performance.

10.2 Alternate Application Circuit

Figure 10-3 shows the alternate application schematic using the CC2651R3SIPA module. This circuit
implementation should be used when the 4-layer stackup and layout recommendations in
be followed, and thus the alternate layout guidelines in
be assembled when using the integrated antenna option within the module. C14 should be assembled if the
module is to be used with an external antenna, in which case its recommended to follow the typical application
circuit as outlined in Section
