Within the terahertz technology gap lies a vast reserve of bandwidth poised for development. However, creating user-friendly technologies capable of generating, manipulating, and detecting radiation within these frequency bands is not only technically challenging but has also been hindered by the limitations of available THz-capable components. That is until we developed our MMW isolators. Read [...]
Multipaction Analysis for Millimeter-Wave Hybrid Circulators Multipaction [1, 2] is a phenomenon occurring primarily in RF systems operating in a vacuum, such as those found on space-based platforms. RF fields accelerate charged particles (electrons), which gain energy and collide with surfaces. If the impact energy is sufficient, additional electrons are released from the surface. The [...]
VDI manufactures extenders for new, compact USB VNAs. The company can extend the test and measurement capabilities up to the lower end of the THz regime (400 GHz) bridging the gap between low cost and high performance. The enabling technology for VDI is our patent-pending millimeter wave hybrid circulator (150 to 190 GHz). Read the [...]
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 [...]
