Conventional communication circuits are unable to send and receive signals simultaneously, which limits communication throughput. Systems involving magnets are similarly restricted to transmission in a single direction, due to the magnetic field generated by magnets.
University of Utah researchers have developed a magnet-less ring combiner that enables full duplex communication, which provides simultaneous transmission and reception of signals. This combiner is configurable with n-number of ports, while maintaining a smaller overall size, reducing manufacturing costs, and enhancing performance. Combiners can be coupled with various switched output port configurations including a SP3T using a 6-way ring combiner.
