Abstract This paper presents a family of four-port electronic circulators adhering to a new topology symmetry that enables linear, low-loss transistor-based circuit implementations. The underlying principle of operation employs a property of the $$90

In-band full duplex (IBFD) communication systems have attracted much interest due to their ability to double the spectrum efficiency by simultaneously transmitting and receiving (STAR) over the same bandwidth. Modern communication technologies have t

Integration of the ferrite devices in the RF front-end and active antennas is hindered by the need for external magnets, biasing soft microwave ferrites. The hexaferrite-based self-biased nonreciprocal devices can operate without external magnets at

Abstract One of the most important components in the radar and microwave industry that provides transmitting and receiving features for an antenna at the same time is called a circulator. Ferrite circulators are passive three‐port devices in which
