Since 1990
McManus Microwave was formed in 1990 to supply state-of-the-art ferrite components and sub-systems to the microwave systems market. Today the company specializes in sub-miniature, broad-bandwidth and high-power circulators, isolators and other devices that are difficult to find anywhere else — and can design and produce almost any ferrite device.
Ferrite Circulator & Isolator Range
McManus specializes in sub-miniature, broad-bandwidth and high-power circulators and isolators — and can design and produce almost any ferrite device to customer specification.
Ferrite circulators across VHF, UHF and microwave bands — most custom-built to the customer's frequency, power and size requirements.
Learn moreFerrite isolators protecting sources from reflected power, with high isolation and low insertion loss in compact packages.
Learn moreSub-miniature circulators and isolators for space-constrained assemblies where standard parts won't fit.
Learn moreRF power capabilities above 100 kilowatts average, with peak power levels above 200 kilowatts.
Learn moreCryogenic devices operating to 77 °K and below, plus units spanning very broad temperature ranges (0 °C to +185 °C).
Learn moreBandwidths to 100% and wider, with high performance such as 40 dB minimum isolation for a single-junction circulator.
Learn moreMost McManus products are custom-made circulators and isolators built to the customer's exact specification. The figures below are the edges of their capability envelope — tell us your requirement and they'll match it.
The McManus catalogue lists dozens of specific circulator and isolator models, predominantly across the VHF/UHF bands. Most are custom-made to order and built to customer specification.
Custom-built ferrite circulators across VHF, UHF and microwave bands (20 MHz–20 GHz), engineered to the customer's frequency, power and size requirements.
