Technical Challenges

The extremely low stray reflection tolerance of -100dB is a very ambitious target, and we will meet it using multiple very high quality isolators based on quasi-optical Faraday rotators that we design and produce in house. An example of the implementation is shown below:



We have produced QO Faraday rotators with greater than 60dB isolation at a spot frequency and 40dB over a 5GHz bandwidth. We will use multiples of the arrangement shown above with very good quasi-optical loads.
