For RSM, RHB, and RGZ, power dissipation of 2 W and an ambient temperature of 70°C is assumed. For YFV, power dissipation of 1.3 W and ambient temperature of 25°C is assumed.

Very few external components are required for the operation of the CC2640R2F device. This section provides some general information about the various configuration options when using the CC2640R2F in an application, and then shows two examples of application circuits with schematics and layout. This is only a small selection of the many application circuit examples available as complete reference designs from the product folder on www.ti.com.

Figure 10-1 shows the various RF front-end configuration options. The RF front end can be used in differentialor single-ended configurations with the options of having internal or external biasing. These options allow for various trade-offs between cost, board space, and RF performance. Differential operation with external bias gives the best performance while single-ended operation with internal bias gives the least amount of external components and the lowest power consumption. Reference designs exist for each of these options.
