implementation to confirm system functionality.

7.1 Application Information

The TRF2001 is a FEM typically used with wireless SoCs to extend the communication range beyond what the

SoCs are natively capable of, and to provide an improved link budget. The primary application of the TRF2001 is

in the ISM band frequency range of 860MHz to 930MHz.

7.2 Typical Application

7.2.1 TRF2001 as Range Extender

Figure 7-1 shows a typical application of the TRF2001 when used as a range extender, paired with CC1314R10

or similar wireless MCUs.
