Author_Institution :
Sony Corp., Yokohama, Japan
Abstract :
An overview of the current status of Japanese microwave ferrite technology is presented. Some recent progress and topics in microwave isolators and circulators are discussed. Special emphasis is placed on recent developments in state-of-the-art YIG (yttrium iron garnet) thin-film devices. Particular attention is given here to filters, oscillators, and a magnetostatic-wave S/N enhancer. Possible future applications of the technology in consumer electronics are projected.<>
