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.
