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.
