Seems like a good connection. It's possible Microphase has multiple joint ventures, but here's an excerpt from an Amplitech PR from Feb '15:

CEO Fawad Maqbool further added, “We also are working on creating a joint venture with our strategic partner, Microphase Corporation, to co-design and support the anticipated new product lines. There will be a bidirectional exchange of products between all divisions to promote more efficient technology development and maintain product excellence. We are confident that this new path will lead to substantial growth and an exciting new beginning for the company.”
