Ferrite Microwave Technologies’ high power WR1800 Waveguide UHF Band Circulators are manufactured for scientific research applications. The components manufactured by FMT are designed to provide high reliability and ultra-precise performance in settings where failure cannot be tolerated. Typically, this style of high power circulator is used for source protection with Magnetrons, TWT’s, Klystrons, and Solid State Amplifiers, among other applications and settings.

WR1800 Waveguide UHF Band Circulators: FMT Capabilities
We offer a broad range of both three-port junction style and four-port differential phase shift circulators for high-power applications. Depending on power and output mismatch conditions, cooling is performed by either (1) air or (2) liquid. All of Ferrite Microwave Technologies circulators maintain superior isolation with very low insertion loss. We utilize state-of-the-art FEA simulations tools, for both RF and mechanical performance and overall functionality.
Our engineers work in partnership with our clients to custom-produce the most cost-effective methods to meet their requirements. Whether developing new products, redesigning current or obsolete components, or providing support and repair services – you can count on the advanced microwave engineering team at FMT.
