Micro Harmonics develops ferrite based millimeter-wave and sub-millimeter-wave components. The company was founded in 2008 as a specialized research and design consultancy for microwave, millimeter-wave and sub-millimeter-wave components and systems. In 2015 they were awarded a NASA Phase I SBIR to develop an advanced line of Faraday rotation isolators and circulators in bands from WR-15 through WR-3 (50 to 320 GHz). NASA has extended that program to a Phase II grant that ends in April 2018.
They have demonstrated working isolators in WR-12, WR-10 and WR-8 and will soon have prototypes at WR-6.5 and WR-5.1. They plan to develop a full line of commercial ferrite components operating from 50 GHz to 320 GHz with significantly improved performance over the current state-of-the-art solutions.
