    Abstract: A phased array may include a clock stage configured to generate shifted clock signals. Each shifted clock signal may include a different phase. The phased array may also include a beamforming stage configured to generate a beamformed signal that includes a beam formed in a direction based on summed signals. In addition, the phased array may include slices. Each slice may include a filter stage and a feedback stage. The filter stage may be configured to generate a corresponding summed signal by filtering a portion of blocker and noise interference in a corresponding receive signal based on blocking signals and the shifted clock signals. The feedback stage may be configured to generate the blocking signals based on the shifted clock signals and the corresponding summed signal. The blocking signals may be representative of the blocker and noise interference in the corresponding receive signal.
