Abstract: Certain aspects of the present disclosure are directed towards apparatus and techniques for receiver calibration. An example apparatus generally includes: a first receiver having a first oscillating signal generation circuit, an output of the first oscillating signal generation circuit being coupled to an input of a first splitter, wherein the first splitter has multiple outputs; a second receiver having a second oscillating signal generation circuit coupled to an LO input of each of a first plurality of mixers of the second receiver; and signal paths between the multiple outputs of the first splitter and signal inputs of the first plurality of mixers, respectively.
