Photonis Defense manufactures a wide range of Power Tubes for Defense purposes that are reliable, sturdy and efficient while still offering dependable performance under tough and severe environmental conditions, including shock and vibration. For operations in high-temperature environments, many of Photonis’ power tubes are forced-air-cooled to ensure reliable low-temperature operation.  Photonis tubes are versatile and can be used for RF amplification, pulsed RF amplification, linear RF amplification, modern data transmissions, and communication systems. Some have also been used for pulsed RF oscillators, regulators, distributed amplifier services and more. No specific application requires the exact same requirements, so Photonis’ Power Tubes for Defense come in a variety of sizes for airborne, mobile, and stationary defense applications. 

Power Tube Cavities

For many years, Photonis Defense has been developing specialized circuitry for power tubes, generally termed “cavities” as a result of customer demand. These cavities are complete RF circuits that are necessary to tune and operate a matching power tube. Each cavity is designed to match a specific tube in order to produce a final high-power amplifier stage for a specific frequency band and service. Each cavity is an essential part of the installation and maintenance operations needed for a Photonis Defense Power Tube. Photonis Defense highly recommends pairing one of our cavities with any recommended matching power tube and can work with you to determine which power tube cavity your application requires.
