When using this IC, the following external components should be used:

CRF:

This capacitor is used for RF de-coupling and must be used for all applications.

100pF is recommended.

Cbypass: This capacitor is used for DC line filtering. 100pF is recommended.

In the case that Rx1 is not used, the processing of the pin is as follows:

• Rx1 is recommended to be open.

• CTLD/GNG4B should be grounded as a DC.
