CORE COMPETENCIES
Micro Harmonics specializes in ferrite components for mm-wave frequencies from 25-400 GHz. Every product that we make offers unique capabilities that distinguish it from any competing technology. Our components find use in a wide range of MMW systems including test & measurement equipment, portal security, telecommunications, scanners, and radar.
DIFFERENTIATORS
 |
Our millimeter-wave ferrite components are the most advanced in the global market. Our isolators have the industry’s lowest insertion loss by a wide margin. They employ diamond heatsinks, giving them the highest power handling capability on the market. Micro Harmonics has developed a full line of isolators optimized for cryogenic applications. |
| . | . |
 |
Our Y-junction circulators have the lowest insertion loss and broadest bandwidth in the industry. Our patented millimeter-wave hybrid circulators have an order of magnitude higher bandwidth than traditional Y-junction circulators and are thus an enabling technology for broadband telecommunications and radar applications. |
| . | . |
 |
Micro Harmonics has developed a line of voltage variable attenuators for mm-Wave systems based on the physics of Faraday rotation. They offer improved power handling and higher bandwidth than other available technologies. |

Customers use our products when they need the absolute highest performance in their mm-wave systems. Micro Harmonics has a unique and sophisticated test and measurement facility with all of the equipment necessary to make comprehensive vector measurements from a few hundred MHz to over 400 GHz. We provide RF test data for each and every component that we ship. |
Company Data
Micro Harmonics was founded as a millimeter-wave (MMW) design consultancy in 2008. The company currently employs ten people. In 2015 the company began developing a line of ferrite components for NASA. The initial components were high-frequency MMW isolators and circulators used to suppress standing waves and direct signal flow in MMW systems. In 2018 the product line was expanded to include cryogenic MMW isolators and voltage variable attenuators. These components were targeted for NASA instrumentation but also find wide application in the commercial, scientific, and military sectors.
In 2020, Micro Harmonics invented and patented an all new MMW hybrid circulator with significantly higher bandwidth than the previous state-of-the-art. This component will enable ultra-broadband telecommunications links for emerging 5G/6G applications.
SBIR/STTR
Micro Harmonics has been working with NASA to develop MMW technology since 2015. MHC has been awarded six SBIR’s to develop state-of-the-art ferrite components for MMW and THz systems. Every SBIR has resulted in a commercialized product line: compact wideband Faraday rotation isolators optimized for either room temperature or cryogenic applications, wide band Y-junction circulators, voltage variable attenuators, and our patented hybrid circulators.
According to the SBIR/STTR Commercialization Report to Congress (9/15/14), “A significant advantage to Phase I/II award winners is that Federal agencies may pursue sole source contracts to utilize technology developed through prior SBIR/STTR awards…”

PAST PERFORMANCE
International Cryogenic Customers |
Micro Harmonics Corporation (MHC) was asked by an international institution to develop a cryogenic isolator in a non-traditional band (W-9, 82-123 GHz) for both room temperature and cryogenic applications. These isolators are also useful for multiplier chains in THz systems. MHC designed a very low-profile cryogenic isolator in W-band for the Rutherford Appleton Laboratory to be used in the Sardinia Radio Telescope receiver in Europe. Our miniature design allows for over thirty adjacent isolators to fit into the system. Unlike standard isolators, MHC isolators are not affected by external magnetic fields, so they are a perfect solution for a tight system requiring adjacent units. |
