Everything RF publishes article detailing our specialization in high performance, high frequency mm-wave circulators.

“‘At first, we couldn’t find anybody that was capable of producing circulators in the frequency band we required, much less with the high isolation and wide bandwidth we wanted,’ says (Fred) Daneshgaran. In a continued search for a circulator with the necessary attributes, Daneshgaran and his team learned of Micro Harmonics, who had developed a circulator for mmWave systems while working with NASA on a number of SBIR projects. Micro Harmonics Corporation specializes in components for mmWave applications and successfully developed an advanced line of circulators operating from 25 GHz up to 150 GHz.”

Micro Harmonics components are solving standing wave issues commonly associated with advancements in wireless technologies. Thank you, Applied Wireless Technology for the recent article!

“One of the major issue design engineers face, as they try to utilize the higher frequencies of the mmWave spectrum, is with isolators. This part of the RF spectrum is critical for the future of wireless technologies like autonomous vehicles, the Internet of Things, 5G and onto 6G, as well as a host of other products. There simply is not enough room at the lower frequencies to handle the bandwidth required of next-gen wireless products, but moving into the higher, millimeter wave spectrum means dealing with a major issue – that of standing waves.”  Dr. Dave Rizzo in Applied Wireless Technology

Micro Harmonics is pleased to announce $75,000 in new funding from the Center for Innovative Technology CRCF SBIR Matching Funds Program. 

MHC identified a need for their cryogenic isolators in high-frequency ship radar and drone inspection systems, particularly in the KA band (WR-28, 26.5-40.0 GHz). These systems need ultra-light, small envelope solutions, features in which MHC leads the market. 

“I am pleased to congratulate Micro Harmonics Corporation (MHC) on their second CRCF award,” said Ed Albrigo, President and CEO of CIT. “This Fincastle, Virginia-based company is innovating in a field where advancements are critical to many industries, including scientific instruments and unmanned systems. We are proud to support the deeply experienced MHC team and look forward to their continued success in the Commonwealth.”

Micro Harmonics was just awarded a NASA Phase II SBIR contract to develop cryogenic Faraday rotation isolators in every band from WR-15 (50-75 GHz) through WR-3.4 (220-330 GHz). In the course of this research effort we will also develop room temperature isolators at WR2.8 (260-400 GHz) and WR-2.2 (330-500 GHz) as well as a line of voltage variable attenuators in the bands WR-15 through WR-8 (90-140 GHz). The attenuators will operate over full waveguide bands with a power rating near 1 W.
