10 Application, Implementation, and Layout

Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI's customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.

10.1 Typical Application Circuit

Figure 10-1 shows the typical application schematic using the CC2651R3SIPA module. Note that C15 should be
assembled when using the integrated antenna option within the module and when the layout design guidelines
in Section 10.4.2 are strictly followed. If the layout guidelines described in
is recommended to implement the alternate application circuit schematic in
layout guidelines in Section
If using the external antenna option, C14 should be assembled. In addition, Pin 15 of the module should be
connected to GND as shown in
Design Files.
The following guidelines are recommended for implementation of the RF design when using an
external antenna on the RF path, pin 14:
• Ensure an RF path is designed with an impedance of 50 Ω.
• Tuning of the antenna impedance π matching network is recommended after manufacturing of the
PCB to account for PCB parasitics.
• π or L matching and tuning may be required between RF out path, pin 14, and the external
connection as shown in
