Abstract: Systems and techniques for distributing reference signals are disclosed. For example, a method includes generating, by a first phase-locked loop (PLL) included in a first beamformer (BF) chip, a first local oscillator (LO) signal; generating, by a second PLL included in a second BF chip, a second LO signal; and in a first BF configuration, transmitting radio frequency (RF) signals by a plurality of antenna elements based on the first LO signal. A first subset of the plurality of the antenna elements is associated with the first BF chip and a second subset of the plurality of antenna elements is associated with the second BF chip. The method includes, in a second BF configuration, receiving RF signals by the first subset of the plurality of antenna elements and the second subset of the plurality of antenna elements based on the second LO signal.
