Reference circuitry
To ensure good RF performance when designing PCBs, it is highly recommended to use the PCB layouts and component values provided by Nordic Semiconductor.
Documentation for the different package reference circuits, including Altium Designer files, PCB layout files, and PCB production files can be downloaded from www.nordicsemi.com.
In this section, there are reference circuits for all product variants, showing the components and component values to support on-chip features in a design.
