Micro Harmonics Is Extending Its Line Of Faraday Rotation Isolators From WR-12 (60-90 GHz) To WR-3.4 (220-325 GHz)

Micro Harmonics is extending its line of Faraday rotation isolators from WR-12 (60-90 GHz) to WR-3.4 (220-325 GHz). Prototypes are currently being evaluated at WR-5.1, WR-4.3 and WR-3.4 and will be released soon. These products are for applications requiring superior isolation and low insertion loss. Power handling exceeds the current state-of-the-art due to the implementation of diamond substrates to channel heat to the waveguide block.

Micro Harmonics has also developed a drop-in isolator topology comprising a center plate that houses the core assembly and an E-plane split waveguide block containing a stepped waveguide twist on both the input and output ports. This topology can be used as a standalone component or the center plate can be removed and integrated into a larger system.

Furthermore, Micro Harmonics announces the availability of its initial circulator product offering, the YC148, covering the 58 to 64 GHz frequency range.  This is the first of a planned line of commercially available circulators operating in sub-bands from 50 GHz to over 140 GHz with significantly improved performance over the current state-of-the-art.

These precision ferrite isolator and circulator products were developed in part by SBIR funding for use on future NASA programs requiring critical performance technology for submillimeter missions. Commercial uses include scientific instrumentation applications such as plasma diagnostics, chemical spectroscopy, biomaterial analysis, point-to-point radio links, portal security systems and radio astronomy.

Micro Harmonics specializes in ferrite based MMW components. The company was founded in 2008 as a research and design consultancy for microwave, millimeter-wave and sub-millimeter-wave components. Micro Harmonics produces an advanced line of Faraday rotation isolators and circulators in bands from WR-15 through WR-3 (50 to 325 GHz).  More information can be accessed at the link below. http://www.microharmonics.com/products/isolators.html
