Microwave Tubes – Travelling Wave Tubes (TWTs), Magnetrons and Klystrons
At TMD we understand microwave tubes.
We've been immersed in the research, design and manufacture of electron devices since their inception, delivering solutions into some of the most demanding applications, supporting our customers’ requirements.
Our tube engineering 'DNA' extends back over 60 years, to EMI Electronics' high power klystron developments during WWII. Since then TMD has been instrumental in many of the industry's major TWT, magnetron and klystron developments.
We design and build high reliability Microwave Tubes for Radar, EW and Communications applications. In particular TMD specialises in ring bar and ring loop TWTs from 1-18 GHz with the following features:
- High reliability dispenser cathode technology (up to 90,000 hrs operation achieved for S band Watchman ATC radar)
- European “Centre of Excellence” for cathode and electron gun design – Download cathode technical whitepaper
- In-house cathode technology minimising reliance on ITAR controlled parts
- Fast warm (under 3 seconds) versions available in Ku band
Emission testing and surface analysis facilities in-house - Air, land and sea platforms supported
TMD also designs and manufactures fixed frequency, agile and tuneable Magnetrons; L, C, X and Ku band.
