Ferrite Microwave Technologies is the leading global manufacturer of WR975 Waveguide UHF Band, 75 kW circulators for industrial applications. FMT supplies advanced circulators to the world’s leading generator companies and microwave industry OEMs. We are supported by our partners at Mega Industries (A Microwave Techniques Company) and their compatible product line, making us the largest global producer of high-power WR975 waveguide components.
WR975 Waveguide Circulator, 915 MHz, 75 kW, UHF Band
Ferrite Microwave Technologies WR975 Waveguide UHF Band Circulator operates at 915 MHz, with input power at 75 kW CW. Our circulators feature one hundred percent copper domes for superior thermal management, leading to lower insertion loss. This passive device includes ports for couplers and/or arc detectors. FMT circulators are the de facto standard for the industrial microwave generator industry. In fact, we install them in our own microwave generators.
FMT Circulators: Applications
Ferrite’s circulators are employed in various applications. Regardless of the application, we place the same level of intricate detail into our high-power microwave components, whether medical, scientific, radar, or industrial. We take a range of application and setting factors into account, from environmental specifications, to power level and operating frequency, to system interface, and beyond. FMT considers each of these factors as critical when designing circulators.
Our WR975 Waveguide UHF Band Circulators at 75 kW are installed in our very own GET2024 915 MHz microwave generators, which are employed in several different industrial processing applications, including:
- Food Processing
- Microwave Pyrolysis
- CVD Diamond Growth
- Energy (Oil Reclamation & Coal Treatment)
- Government Municipalities (waste and sludge treatment)
- Building & Materials Handling (lumber, foam, and textiles treatment)
