Abstract: A method of wireless communication includes receiving a first beam using a first antenna device during an occasion of a reference signal. The method further includes receiving a second beam using a second antenna device that is distinct from the first antenna device during the occasion of the reference signal. Receiving the first beam and the second beam includes inputting, to a modem, a representation of a combination of the first beam and the second beam. Receiving the first beam and the second beam further includes generating, by the modem based on the representation, a first signal associated with the first beam using a first parameter associated with the first antenna device and a second signal associated with the second beam using a second parameter associated with the second antenna device.

Abstract: Certain aspects of the present disclosure generally relate to circuitry and techniques for digital-to-analog conversion. One example system for digital-to-analog conversion generally includes a first digital-to-analog converter (DAC) having an input coupled to an input node of the system and a mixing-mode DAC having an input coupled to an input node of the system. The mixing-mode DAC may include a second DAC and a mixer, an output of the second DAC being coupled to an input of the mixer. The system may also include a combiner, wherein an output of the first DAC is coupled to a first input of the combiner, and wherein an output of the mixer is coupled to a second input of the combiner.
