• Are you a high tech start up or small to medium sized business?
  • Are you frustrated that you lack the in-house expertise in RF and Microwave engineering design to achieve your business goals?
  • Worried about the cost of hiring a full time employee but also keen to bring in the skills and experience you need?

My name is Keith Alexander, I am a highly experienced RF design engineer dedicated to helping my clients develop new designs in RF and microwave systems.

I work with you to understand your product and market so that you can develop the systems and products you need to serve that market and grow your business.

I am focused on both project and design work so that you can develop the products you need in house, as well as delivering skills and expertise where you need it most.

I work from a laboratory fully equipped to 20GHz and upward.

Bringing technical and commercial advantage to clients needing RF technology for their businesses.

My name is Keith Alexander and I am an electronic design engineer with a strong background in RF and Microwave engineering – I built my first crystal radio from a kit when I was seven, my first short wave radio at eleven and more than fifty years later I’m still passionate about radio technology!
