For applications and operations that require amplification of the millimeter microwave frequency, Photonis Defense offers a selection of MM Wave Traveling Wave Tubes to fulfill these requirements. Photonis’ MM Wave tubes cover standard waveguide bandwidths but can also be optimized to cover small bands of interest if necessary. These tubes are helix-type traveling wave tubes constructed using the industry standard of metal-ceramic. Their construction makes the tubes not only lightweight and rugged, but it also provides adequate protection and durability for operations taking place in severe environments. Photonis’ traveling wave tubes also feature rare-earth periodic permanent magnets that allow for power-free focusing of the tube. These MM Traveling Wave Tubes are suitable for military airborne or ground-based platforms and can be ordered as fully developed systems or you can work with Photonis to custom design a system specific to your requirements.
