Specifications and Ordering
Our designs are built onsite and upon request. We tailor each order through our sales engineers to better serve your purchase.

QuinStar’s Fullband Junction Circulators & Isolators come in two waveguide bands covering the frequency range of 18 – 40 GHz. These H-plane three-port Y-junction ferrite devices feature high isolation, low insertion loss, and full waveguide bandwidth.
Junction circulators and isolators provide load isolation in a wide variety of components such as Gunn oscillators and amplifiers, upconverters, down-converters, and power combiners. They also function as duplexers at the antenna ports of millimeter-wave transceiver systems. Finally, Fullband Junction Circulators & Isolators work well in broadband or swept frequency applications.
