Abstract: In an embodiment, an apparatus includes a first digital beamformer (DBF) associated with a first subset of antennas of a phased array antenna, the first DBF including a transmit section associated with transmission of a first signal at a first frequency in a transmit mode and a receive section associated with receiving of a second signal at a second frequency in a receive mode, the second frequency being different from the first frequency. The apparatus includes a second DBF associated with a second subset of antennas of the phased array antenna. The first and second DBFs are configured to receive a local oscillator signal having the first frequency from a common local oscillator in the transmit mode and receive the local oscillator signal having the second frequency from the common local oscillator in the receive mode.

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.
