Precision-Junction-Circulators-and-Isolators 2

QuinStar Technology's QJY series precision junction circulators and QJI series precision junction isolators are available in seven waveguide bands covering the frequency range of 18 to 110 GHz. Single-junction isolators and single- and three- junction circulator versions are offered. These three-port Y-junction ferrite devices feature high isolation, low insertion loss, and broad bandwidth. The three-junction circulators effectively combine a standard circulator with input and output isolators in a compact package. Junction circulators and isolators are used to provide load isolation in a wide variety of components including Gunn and IMPATT oscillators and amplifiers, Upconverters and downconverters, power combiners, and also as duplexers at the antenna ports of millimeter-wave transceiver systems.
