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. |
