Abstract

Certain aspects of the present disclosure generally relate to radio frequency (RF) front-end circuitry. For example, certain aspects provide an apparatus having a first converter circuit configured to upconvert a first baseband (BB) signal to a first RF signal based on a mode of operation, and a second converter circuit configured to upconvert a second BB signal to a second RF signal based on the mode of operation. The apparatus also includes a first RF weight adjustment circuit configured to selectively apply an amplitude weight or a phase weight to at least one of the first RF signal or the second RF signal based on the mode of operation, and a controller configured to control a power state of the second converter circuit in dependence on the mode of operation.
