Abstract:
Embodiments of the present disclosure describe apparatuses, methods, and systems of front end module (FEM) having a feedback path that includes a passive attenuation network. The passive attenuation network may provide a feedback signal to a receive output port of the FEM that may be used as a basis for predistortion. Other embodiments may also be described and/or claimed.
