About me.

My name is Keith Alexander and I am an electronic design engineer.

I have 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!

What do I do?

I work with high tech start-ups and SMEs who need an in-house RF design engineering expert but don’t want the high cost and attendant risk of hiring a permanent employee.

As an RF/Microwave design engineer with more than 40 years’ experience, I can provide the design expertise which companies need, especially in relation to RF design.

My background means that I can offer the support and advice essential to healthy growth for new businesses.

I love helping my clients develop the intellectual property and design solutions that are vital to their success, leaving them able to focus on building their business.

Despite my enthusiasm for radio technology, I have never lost sight of its purpose: bringing commercial advantage to your business. No amount of radio technology is worthwhile if it does not add value and bring profit to your business or your shareholders.

That’s why I like to focus on helping high tech companies who struggle with complex RF and microwave design projects, and who need the expertise and design help that I can provide.

My clients are typically looking for help on a consultancy basis or a one-off project, helping them develop products and designs cost effectively and quickly.

I am both passionate about RF engineering and dedicated to working with my clients to provide the support, advice and expertise that they need to succeed.
