ACHIEVING BREAKTHROUGHS IN MAGNET-FREE CIRCULATOR TECHNOLOGY

In many communication systems, isolators and circulators are of fundamental importance, as they protect sources from self-interference and allow full-duplex functionality. In lay terms, circulators enable transmission and receipt of signals in the same frequency channel at the same time. At present, this operation can only be achieved with magnetic devices, which are bulky, heavy, expensive, and cannot be integrated on a chip. Silicon Audio is applying its core competencies and mechanical and electrical engineering capabilities to realize full-duplex functionality based on circulators without the use of magnets, creating the potential for novel applications using a new generation of magnet-free circulators.
