A 60-year-old theory is changing the game for millimeter-wave attenuators (MMW). An article published in New Electronics explains how engineers have long relied on PIN diodes and resistive vane attenuators to manage signal strength. Yet, both come with serious tradeoffs at high frequencies. Now, a breakthrough in Faraday rotation is unlocking a third path forward, [...]
Electronic Specifier had a lot to say about our MMW isolators in an article discussing the future of sub-THz amplifiers. In essence: “By adopting new isolator designs, engineers can significantly reduce insertion loss, improve thermal management, and optimize system performance. Advanced isolators not only ensure that millimeter-wave amplifiers maintain peak efficiency but also enhance reliability and [...]
Micro Harmonics has been leveraging the Faraday Rotation principle to advance millimeter-wave (MMW) components into the sub-THz regime. As part of this effort, we recently unveiled our Faraday rotation attenuators. The response has been amazing, and Design Solutions recently featured them in an article. These attenuators provide full waveguide band operation and superior power handling [...]
While an amplifier may function optimally with a well-matched load – such as a power meter – its performance can degrade significantly when the load is not well-matched. Since power amplifier manufacturers cannot dictate the specific load impedance in their customers’ systems, they incorporate isolators to maintain consistent performance. However, as a recent article in [...]

Microwave Product Digest published a story about the challenges of using isolators in MMW amplifiers. The article discusses how Micro Harmonics isolators are overcoming the notable drawback of conventional isolators. Among those mentioned in the article is the issue of insertion loss. Traditional isolators operating in the D-band (WR-6.5, 110-170 GHz) can have insertion losses [...]
Our new Faraday rotation-based attenuators are particularly well-suited for applications in telecommunications, radar systems, and test and measurement equipment operating at mm-wave frequencies. Their combination of high dynamic range, low insertion loss, and compact size makes them ideal for field use in aerospace and defense systems, where both performance and portability are critical.

Our new Faraday rotation attenuators were just featured in an article published in Design2Part magazine. These attenuators utilize a magnetic coil to produce a variable magnetic bias field in a ferrite rod. They offer full waveguide band operation and high-power handling compared to other technologies.

When the strength or magnitude of a radio frequency (RF) signal must be reduced, attenuators are traditionally relied upon. They are especially useful for signal leveling or switching applications. At frequencies above 50 GHz, two electronically tunable variable attenuator technologies are most often employed: PIN diode and resistive vane attenuators. However, as outlined in a [...]
The move up the electromagnetic spectrum (EM) into millimeter waves (MMW) is proving to be a double-edged sword. System designers eager to leverage wider bandwidths and incredibly high data throughputs must also contend with a host of new challenges. Of amplified importance – particularly between 75-330 GHz – is the issue of attenuation. Read more [...]
