Faraday rotation isolators designed for room temperature operation do not work well at cryogenic temperatures. The primary cause is temperature-dependent ferrite magnetization. Everything RF recently published a technical paper written by Micro Harmonics Founder, David Porterfield that addresses how to achieve optimal performance in a Faraday rotation isolator at cryogenic temperatures. Read the full article [...]
The call for ‘more D band’ has gone out. With the ability to transmit 100 Gigabits per second (Gbps), the D band will unlock a number of technologies across a wide range of industries. Electronic Specifier recently published an article featuring Micro Harmonics and how our millimeter wave components are helping to unlock commercial applications [...]
Two Methods for Realizing Millimeter Wave Isolators There are two fundamentally different techniques for designing isolators at millimeter-wave (MMW) frequencies. Maybe you have noticed this if you ever wondered why some isolators are narrow-band and some operate across the full waveguide band. Or maybe you noticed that some isolators are built with a terminated third [...]
Everything RF recently published an article that discussed the issue of reflected waves at D band. The story looks at NI which had been trying to deliver reliable test, measurement and prototyping equipment for D band, but was struggling with mismatched waves. The solution was to use our millimeter wave isolators. Read the full story [...]
Micro Harmonics CEO, David Porterfield, was quoted in an article that recently published in Electronics World where the publication attempts to answer a key question: ‘can the infrastructure for D band be built out within the next 5-10 years allowing the impending move up the EM spectrum.

The Electric Current Magazine featured our millimeter wave hybrid circulators in a story in this month’s print issue. To learn more about how hybrid circulators are enabling engineers to operate at sub-THz frequencies, read the story here:
Some Interesting Facts about Rectangular Waveguides David W. Porterfield, Ph.D., Micro Harmonics Corporation Rectangular waveguides are commonly used in mm-wave applications primarily because they are the lowest loss transmission media at these frequencies. They are single-moded over broad bandwidths and provide isolation from external RF signals. In this post, we will review some other interesting [...]
Today, Inc. Magazine announced that Micro Harmonics Corporation (MHC) has once again ranked as one of the fastest-growing private companies in America. After two consecutive years on the Regional Inc. 5000 list, MHC makes its first appearance on the Inc. 5000 national list, coming in at number 3,736. You can read the press release here.
Electronic Products Test & Design featured an article written by our COO, Diane Kees, in their August 2023 issue. The story, titled: Exploring the Wealth of Opportunities in the D-band, was featured on the cover and is on page 28. You can read the full article here.
The Difficulties in Writing Specifications for Millimeter-Wave Components Introduction We often accept a manufacturer’s specification of their millimeter wave components without a second thought. But a survey of the industry will reveal that what one manufacturer means by, for example, “20 dB isolation” could be a very different standard of performance from another manufacturer who makes [...]
