My first year as a Director has indeed been challenging and I have seen more change in the last 12 months than the preceding 12 years working for the company! The pandemic forced all of us to quickly adapt to the way in which we work and the way we live our lives.

For many of us this will be the first time we have faced such restrictions to our liberty, unlike our predecessors who had to endure far greater suffering in their lives. This was epitomised in the UK by Captain Sir Tom Moore who served his country in the second world war and spent his 100th year fundraising over £30M for the National Health Service. He sadly passed away in February but his spirit and never give up attitude was an inspiration to so many as we moved through 2020.

At TMD we reacted to the pandemic quickly and even before the first lockdown was announced in March 2020 the company was implementing changes to our procedures, work place and policies to ensure we were protecting our staff at all costs.

Following the first lockdown only essential workers continued to visit our facility in Hayes, and our US subsidiary in Baltimore implemented similar measures. All other staff were either working from home or furloughed. Weekly bulletins were issued throughout by our Group CEO, Dave Brown, and we invested heavily into PPE and signage throughout the company which were often over and above the government recommendations at the time.

We continued to maintain production throughout and are achieving growth which is an amazing testament to all colleagues at the company. Although there were many examples of pride coming from TMD employees for the way in which the company managed through 2020, perhaps the most rewarding came from our furloughed staff all of whom were protected from financial loss whilst their colleagues kept the wheels turning. The fact that they were fully aware of the unprecedented circumstances that lead to their situation was reflected in the much appreciated message of support received by me, fellow board directors, and co-workers.

Although I am eminently aware that many people have suffered real loss I do not recall a time when I have been prouder to work for TMD.
As we move forward in 2021 the vaccine programme in the UK is advancing at a fast pace and throughout the world we are seeing signs that better times are ahead. I am sure we will still have some bumps in the road but we can now look forward with optimism.

I hope in this version of “In Focus” we will demonstrate the strides TMD is making with investment into new products, our people and our capabilities.



As many of you may know, TMD Technologies has been operating a charity scheme for several years. Charities are nominated by staff and the fund-raising activities are co-ordinated by the company’s Sports & Social Team (SAS). We are pleased to announce that last year we raised £10,000 for CALM (Campaign Against Living Miserably) from a variety of events.

So far, we have supported Alzheimer’s Society, Cancer Research UK, National Autistic Society, London’s Air Ambulance, CALM and this year, Diabetes UK.

We are also doing well with our low frequency, ultra-high-power accelerator amplifiers. The first units have been successfully fielded and we recently attended the IPAC 2019 International Accelerator Exhibition in Melbourne. Here, potential customers were impressed with the high reliability and ‘availability’ of these products – critically important for many applications where the system is required to provide 24/7 operation.”

TMD’s new products are highlighted in the additional colourful icons on the home pages of our UK and USA websites and

Tom Curtin, VP Sales & Business Development, TMD Technologies, LLC (TMD-US)

TMD Technologies in the US is experiencing unprecedented growth in our MPM, HVPS, and commercial amplifier business. As more customers become aware of TMD’s high performance products and proven reliability, the US office has expanded in order to support this growth. Especially relevant is the continued pursuit by the US aerospace defense companies of higher power microwave solutions, and increased demand for higher frequencies. TMD has invested heavily in pursuing these developments and has products ready and in development to address this critical need.

TMD celebrates an outstanding 75 years at the top of scientific and technical microwave and RF innovation

– from the world’s very first high-power radar klystrons to quantum clocks!

TMD’s innovative heritage can be traced right back to the 1940s where, under the then leadership of EMI, the company produced the world’s first high power klystron, the CV150. Subsequent major developments covered travelling wave tubes (TWTs) and magnetrons, leading to a multi-cavity klystron for the UK’s first early warning radar, and the world’s first and only electrostatically focussed klystron produced in volume.


Nigel Hann, Head of Sales, TMD Technologies

I’d like to take this opportunity to summarise where we are with product development at TMD. As always, we strive to remain at the leading edge of high power and high voltage RF and microwave, providing all the features and performance that our customers are looking for. If there’s anything we’ve missed or should be doing differently don’t hesitate to let me, or any of the sales team know and we’ll feedback to TMD’s engineering team at our weekly get-togethers – and in between! Many thanks to those of you who have completed our annual customer surveys. These are important for us to improve quality, reliability, customer service and all aspects of the TMD brand.

I’m delighted to write this message to TMD Technologies’ customers in our 75th Anniversary year. As explained in more detail on page 2, TMD’s heritage can be traced right back to 1944 where, under the then leadership of EMI, the company produced the world’s first high power klystron the CV150 – for use in wartime radar.

It’s fascinating to reflect that this same spirit of innovation is very much alive in TMD’s engineers today, who continuously challenge themselves to be thought-leaders in the RF, microwave and high voltage industry.

However, to be effective, this activity must be closely aligned with markets and customers. I am very proud to head up TMD’s energetic and dedicated Sales & Business Development Team, which is closely and passionately focussed on our customers and the emerging requirements of their applications.
