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 [...]
Microwave Journal recently featured Micro Harmonics’ new hybrid circulators in WR-12 (70 to 86 GHz), WR-10 (85 to 104 GHz) and WR-8 (107 to 133 GHz) millimeter waveguide bands in their June 2023 magazine, as well as online, and on their Frequency Matters podcast. Read the press release here.
How to Choose an Isolator for a Millimeter-Wave System Millimeter-wave (MMW) systems often employ isolators to suppress standing waves and achieve optimal performance. Isolators pass an RF signal traveling in the forward direction while absorbing signals traveling in the reverse direction. The absorbed signal is converted to heat energy in a resistive load internal to [...]
“The D-band is the new E-band” read the shirts worn by Virginia Diodes (VDI) employees at a recent microwave symposium. Covering 60-90 GHz, the E-band is a well-established high-capacity solution for a number of mmWave applications. Advancements in test and measurement equipment are allowing millimeter wave component manufacturers and systems designers to ramp up production [...]
A Comparison of Millimeter-Wave Variable Attenuator Technologies Electronically tunable variable attenuators are useful for signal leveling and switching applications. The desirable characteristics of an attenuator are typically high power handling, high dynamic range, high return loss (low port reflections), a high degree of flatness in the response across the band, low insertion loss, and broad [...]
It is not just telecom that will require the added bandwidth available within the D-band. Industries like military & defense, remote sensing and security, atmospheric science, radio astronomy, and automotive are all racing to unlock these higher frequencies. Read an article from EEDesignIt that discusses how our millimeter wave components are helping system designers move [...]
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 [...]
Advantages of the Hybrid Circulator Introduction Circulators are 3 port components that couple power in a circulating fashion: power from port 1 is coupled to port 2, from port 2 to port 3, and from port 3 to port 1. Circulators are widely deployed in communications and radar systems because they enable a system [...]
“Micro Harmonics has really been innovative in mmWave and THz regime having designed a full line of millimeter wave isolators from 50 to 400 GHz,” states Jeffrey Hesler, Ph.D., CTO of Virginia Diodes, Inc. “In fact, it’s those isolators that enable our extender analyzers to operate at those higher frequencies.” Read the full story in [...]
