  • Patent number: 12040525
    Abstract: A double-disc structure for self-biased circulators monolithically integrated on semiconductors is provided. A self-based circulator is attractive due to the great reduction in its size and weight compared to conventional circulators which have bulk permanent magnets. The development of miniaturized self-biased circulators enables monolithic integration of such circulators directly into monolithic integrated circuits (e.g., monolithic microwave integrated circuits (MMICs)) on a single chip and opens the door to full-duplex communication in radio frequency (RF) bands higher than Ka band, without suffering from the additional losses through connectors. This disclosure demonstrates a new double-disc structure by using two self-biased discs in a circulator device, which greatly improve its insertion loss, isolation, bandwidth, and power handling capability.

  • Patent number: 12040769
    Abstract: Digital step attenuator (DSA) and digital phase shifter (DPS) multi-stage circuit architectures that provide for high resolution. Embodiments use a dithering approach to weight bit positions to provide a much finer resolution than the lowest-valued individual stage. Bit position weights for stages are determined so as to enable selection of combinations of n bit positions that provide a desired total attenuation or phase shift range while allowing utilization of the large number of states (2n) available to produce fractional intermediate steps of attenuation or phase shift. The fractional intermediate steps have a resolution finer than the lowest-valued stage. Bit position weights may be determined using a weighting function, including weightings determined from a linear series, a geometric series, a harmonic series, or alternating variants of such series. In some embodiments, at least one bit position has a fixed value that is not determined by the bit position weighting function.
