David Porterfield, CEO of Micro Harmonics Corporation, wrote a paper for IEEE on a new broadband hybrid circulator that has been developed for use at millimeter-wave (MMW) frequencies. The hybrid circulator comprises a Faraday rotator and an orthomode transducer (OMT) which work together to produce the circulator function. These patent-pending designs can cover 24% fractional bandwidths with low insertion loss and more than 20 dB of isolation. Read the full paper here.

Micro Harmonics Corporation has announced the release of its hybrid circulators in three new millimeter waveguide bands: WR-12 (70-86 GHz), WR-10 (85-104 GHz), and WR-8 (107-133 GHz).
These patent-pending hybrid circulators can cover 24% fractional bandwidths with low insertion loss and more than 20 dB of isolation. Their wideband performance is verified from the comprehensive test data that Micro Harmonics provides with every component.

Micro Harmonics was featured in a recent article in U.S. Tech (print and online) discussing the issues with moving up into mmWave frequencies (click here to download).
“At the D-band, you are looking at 100 Gigabits per second (Gbps). That is a ton of bandwidth,” says Jeffrey Hesler, Ph.D., CTO of Virginia Diodes, Inc. (VDI). “So, everyone is asking the same question, ‘how do we get there?’”
Electronic Specifier spoke with Micro Harmonics CEO for a recent article (click here to download):
“For mmWave component manufacturers like us, this combination of a cost-effective VNA and extender analyzers is a game-changer,” David Porterfield, Founder and CEO of MHC.

Inc. magazine has revealed its fourth annual Inc. 5000 Regionals list and Micro Harmonics is ranked at No. 134. The prestigious ranking of the fastest-growing private companies in the United States offers a unique look at some of the most successful independent businesses in the nation.
“It is an honor to be mentioned among this list of such successful companies,” says David Porterfield, Founder and CEO of Micro Harmonics. “We want to thank all of our amazing customers who trusted us to deliver on improved millimeter wave components.”

The D-band is the new E-band. Covering 60-90 GHz, the E-band is a well-established high-capacity solution for a number of millimeter wave applications. However, there is a growing appetite for more, and meeting that ever-increasing demand for greater data transmitted at higher speeds will require the move up to higher frequencies such as the D-band (110-170 GHz).
The problem is that currently, there is simply not enough infrastructure in place to support such a move. However, as this article (click here to download) from everything RF points out, companies like Virginia Diodes, Inc., Keysight Technologies, and Micro Harmonics Co. | an Inc. 5000 Company are making huge strides to help bridge the gap.
A Gold Rush to D-Band and Beyond (everythingrf.com)
We are honored to have been awarded the 2022 Product of the Year from Electronic Products Magazine. Our Hybrid Circulators won for “Best RF and Microwave Product.”
The patent-pending hybrid circulator is designed for wideband millimeter-wave (mmW) transmit (Tx)/receive (Rx) systems.
It combines an orthomode transducer with a Faraday rotator to achieve more than twice the bandwidth in WR-15 and an order of magnitude of the bandwidth in WR-5.1 compared with the traditional Y-junction design.
The hybrid circulator is claimed as the first to cover the 150- to 190-GHz and the 54- to 68-GHz bands with 20-dB level isolation.

“‘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
