Recently, researchers at IMRA – a creative research and innovation organization that develops essential technologies for industrial use – overcame many of the issues associated with the THz regime when working at frequencies above 300 GHz. In a recent article from eeDesignIt, they detail how our millimeter wave isolators helped advance the research in the [...]
Why Are Y-Junction Circulators Difficult to Find Above 100 GHz Y-junction circulators are used to direct signal flow in millimeter-wave (MMW) transmit and receive systems. At the heart of the device is a ferrite core located at the junction of three waveguides. The magnetically biased ferrite is non-reciprocal which gives rise to the unique circulator [...]
The scientific community is striving to bring life to the so-called “dead zone”, a region of the electromagnetic (EM) spectrum between electronics and optics. This band, often referred to as the “terahertz gap”, resides between 100 GHz and 30 THz. EverythingRF recently published an article mentioning how our isolators are helping bridge the gap. Read [...]
For a 3rd consecutive year, Micro Harmonics has secured its place on the annual Inc. 5000 Regionals List of fastest-growing private companies in the United States. The prestigious list compiled by Inc. Magazine has Micro Harmonics ranked at number 106 in the Mid-Atlantic region. “We take great pride in our consistent growth and are honored [...]
“We were really struggling with bad mismatches in our waveguide system and kept getting these really bad frequency ripples,” explains Ed Loewenstein, Chief Architect at NI – formerly known as National Instruments. Learn how NI was able to overcome these standing waves within the D band in a new article published in Industry Today.
Our founder – and one of the world’s leading experts in Faraday Rotation Isolators, David Porterfield – recently wrote a paper on the science behind why traditional isolators designed for room temperature operation do not work well at cryogenic temperatures. The paper also demonstrates how our newly designed isolators operate with high isolation and low [...]
Fullband mm-Wave Circulators Are on the Horizon Diving into Revolutionary Circulator Developments Circulators are useful in transmit/receive systems, isolating a transmitter from a receiver while allowing them to share a common antenna. For more than 50 years the Y-junction circulator has been the primary implementation at mm-wave frequencies. Commercial Y-junction circulators with full waveguide band [...]
Revolutionizing MMW Systems: The Crucial Role of Cryogenic Isolators Millimeter wave engineers operate in a part of the electromagnetic spectrum where there are some significant challenges to overcome. It is difficult to generate signal power, the available components are costly and sometimes don’t work well, and often the components just don’t exist at these frequencies. [...]
Engineers working within the D band are increasingly looking for better ways to solve the issue of reflected waves. "When you get above 110 GHz, it’s sort of uncharted territory,” explains Ed Loewenstein, Chief Architect at NI. “Your connectivity gets strange, and cables no longer work well. So, most things are done in waveguides.” Signal [...]
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.
