Description
Our conventional traveling wave tubes are of metal-ceramic construction for severe environmental conditions and utilize rare earth periodic permanent magnets for power-free focusing. This combination creates a rugged, light weight device suitable for any military airborne or ground-based platform. Photonis defense offers many qualified products which are capable of continuous RF operation. Many of our conventional traveling wave tubes can also be operated in pulse mode using focus electrodes or shadow grid modulation. The majority of our tubes can be supplied with military grade High Voltage Power Supplies to operate the TWT from various military power sources. Photonis defense offers an extensive selection of fully developed designs but will also work with you to design a TWT to meet your specific requirements.
