Micro Harmonics specializes in ferrite components for use at millimeter-wave (MMW) frequencies from 25-400 GHz. Our products offer unique capabilities that distinguish them from competing technologies: lowest insertion loss, highest power rating, and RF test data for every unit. For a brief explanation of these factors and why they are important to your system, click here!
Our Guarantee: No two MMW components have the same exact frequency response. Unique signatures arise from small misalignments and variations in the internal parts. The differences can be substantial. Max, Min, and typical specs are helpful, but what you need to see are the actual test data for the components you are buying. Micro Harmonics tests every component across the full waveguide band on a vector network analyzer. We supply the test data to the customer at no additional cost. Don’t settle for anything less.
Our products find use in a wide range of MMW systems including test & measurement, portal security, telecommunications, scanners, and radar. We are located in Fincastle, Virginia.

Micro Harmonics produces millimeter wave isolators, millimeter wave circulators, and millimeter wave attenuators operating from 25 GHz to over 400 GHz. These are not copies of 1960’s designs with high insertion loss and large footprints. Our components are designed from the ground up using modern sophisticated electromagnetic simulation tools to achieve the industry’s widest bandwidth and lowest insertion loss in a more compact size. Our isolators employ a unique diamond heatsink to improve power handling and achieve lower operating temperatures for improved reliability. They are simply the most advanced components on the market today.
Founded in 2008 as a specialized research and design consultancy for microwave, millimeter wave, and sub-millimeter-wave components, we remain dedicated to quality components for advancing millimeter-wave technology. In 2015 we were awarded a NASA Phase I SBIR contract and a subsequent Phase II SBIR contract to develop an advanced line of Faraday rotation isolators and circulators in bands from WR-15 through WR-3.4 (50 GHz to 330 GHz). Because of language in the congressional SBIR authorization, our isolators and circulators can be sole sourced in US government acquisitions. Our products are 100% made in the USA.
To our knowledge we are the only supplier of isolators in the WR-3.4 and WR-2.8 bands in the world. All of our isolators exhibit state-of-the-art performance in terms of low insertion loss and high power handling. Each isolator is fully characterized on a vector network analyzer, not spot-checked at a couple of frequencies in the band. They cover full waveguide bands and work very well over extended bands above and below the standard waveguide bands.
In 2019 we began developing Y-junction circulators. Using sophisticated impedance matching and mode control techniques we have demonstrated a WR-15 circulator with more than 6 GHz bandwidth from 58-64 GHz, which is three times the bandwidth of most standard circulators in that frequency range. In WR-12 we developed and demonstrated circulators covering the bands 71-76 GHz and 81-86 GHz. In WR-10 our circulator covers a 5 GHz bandwidth from 90-95 GHz and in WR-8 we have demonstrated 5 GHz bandwidth from 115-120 GHz. We continue to develop Y-junction circulators in sub-bands from 50-120 GHz.
In 2022 Micro Harmonics developed a series of hybrid circulators ranging from 54-333 GHz. The R&D effort was funded through a NASA Phase I and II SBIR contract. The dominant circulator topology in the millimeter-wave (MMW) spectrum is the Y-junction. There are very few commercial Y-junction circulators available above 100 GHz and those tend to have bandwidths near 1-2 GHz. Our hybrid circulator is not a Y-junction, but utilizes a patent pending topology which provides wideband capabilities. For example, the WR-6.5 hybrid circulator operates across the entire 118-150 GHz band. The hybrid circulator topology has the added benefit that it can be configured to attenuate signals travelling from the receiver (Rx) port to the transmitter (Tx) port.
