2.3.2 Package Size and Reference Design

Using the correct reference design for the selected device package size is important. Using a reference design that is not designed for the package size can affect the RF impedance matching and filtering stage (the RF path) and consequentially degrade the RF performance.

For example, using a reference design that was designed for the Sub-1GHz RF path (like the 868-915MHz bands) of an RGZ 7mm × 7mm VQFN package with an RSK 8mm × 8mm VQFN package has sub-optimal RF performance. However, using a reference design for the Sub-1GHz RF path (like the 868-915MHz bands) of an RGZ 7mm × 7mm VQFN package with an RGZ 7mm × 7mm VQFN package has comparable RF performance, and can be reused.

Note: Up-to-date reference designs for the CC131x and CC135x family are maintained in CC13xx/CC26xx Hardware Configuration and PCB Design Considerations application note.
