SWRS301 September 2026 CC1407P
ADVANCE INFORMATION
The following reference designs should be followed closely when implementing designs using the CC1407P 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 CC1407P 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 CC1407P high-power PA output:
