2019 MARKS TMD’s 75TH ANNIVERSARY

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.
