8 Application, Implementation, and Layout

Note

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.

For general design guidelines and hardware configuration guidelines, refer to CC13xx/CC26xx Hardware

Configuration and PCB Design Considerations Application Report.

8.1 Reference Designs

The following reference designs should be followed closely when implementing designs using the CC1404P

device.

Special attention must be paid to RF component placement, decoupling capacitors, and DCDC regulator

components, as well as ground connections for all of these. For optimum RF performance, especially when

using the high-power PA, it is important to accurately follow the reference design with respect to component

values and layout. Failure to do so may lead to reduced RF performance due to balun mismatch. The amplitude

and phase balance through the balun must be <1 dB and <6 degrees, respectively. PCB stack-up is also critical

for proper operation. The C140xP EVMs and characterization boards are using a finished thickness between the

top layer (RF signals) and layer 2 (ground plane) of 175 µm.

The CC1404P has a very flexible RF front-end design that enables many different optimzations. To enable

customers to quickly evaluate the different options we have created different reference designs.

Integrated balun devices can be used, the following balun is recommended for CC1404P high-power PA output:

• Murata LFB21892MBGGF964

8.1.1 Highest Performance

The highest performance design or Full Entitlement (FE) design covers the broadest customer requirements,

including showcasing the new integrated ultra-LNA (uLNA) that enables the integration of SAW filters without the

drawback of losing 2-3dB of receive sensitivity.

• Longest Range (+22dBm transmit)

• Best sensitivity (4dB improvement using uLNA)

• Most robust receive in presence of 5G
