IMPROVE MMW SYSTEM PERFORMANCE

The Best Millimeter Wave Products – Micro Harmonics

Micro Harmonics produces high-quality millimeter wave products including millimeter wave isolators operating from 26-400 GHz, millimeter wave circulators, and millimeter wave voltage variable attenuators. These are the most technologically advanced millimeter wave products on the market today. They are optimized for extended bandwidth and the industry’s lowest insertion loss. Our WR-3.4 isolators have typical insertion loss of less than 2 dB in the band 220-330 GHz! Our patent-pending hybrid circulator achieves 10x the bandwidth of a traditional Y-junction circulator! We also manufacture cryogenic millimeter wave isolators optimized for cryogenic applications. All our ferrite components are 100% made in the USA and can be sole sourced in US government acquisitions.

Building the Future with NASA

Micro Harmonics is proud to partner with NASA to develop some of the best millimeter wave products on the market.

Millimeter-wave Hybrid Circulators

Micro Harmonics has been awarded a NASA Phase I SBIR contract for the development of an all new hybrid circulator for millimeter-wave (MMW) applications. The contract runs from July 2020 through December 2020. In the MMW, the dominant circulator topology is the Y-junction. There are very few commercial Y-junction circulators available above 100 GHz and those tend to have bandwidths near 1-2 GHz. Our hybrid circulator is not a Y-junction and can in theory cover a full rectangular waveguide band (e.g. 110-170 GHz) with inherently high isolation between the Tx and Rx ports. The initial prototype will be designed to cover the band from 150 GHz to 200 GHz. A provisional patent has been filed.

Cryogenic Isolators for MMW Frequencies

Micro Harmonics developed a line of cryogenic  millimeter wave isolators under NASA research contracts that ran from 2019-2021. Cryogenic isolators have been developed in every standard waveguide band from WR-15 (50-75 GHz) to WR-5.1 (140-220 GHz).

Additionally, a line of voltage variable attenuators was developed in the bands WR-15 through WR-10 with plans to develop attenuators in WR-8 and WR-6.5. The attenuators use the physics of Faraday rotation to cover full waveguide bands.

MMW Isolators with Ultra-Low Loss

Micro Harmonics developed a line of ultra-low insertion loss isolators under NASA research contracts that ran from 2015-2018. The isolators cover full waveguide bands from WR-28 (26-40 GHz) through WR-2.8 (260-400 GHz). They have the lowest insertion loss in the industry with less than 2 dB in the WR-3.4 band. Our isolators also have the industry’s smallest form factor. They employ diamond heat spreaders for improved power handling and are resistant to stray magnetic fields.
