Description
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 our power tubes are
forced-air-cooled to ensure reliable low-temperature operation. Photonis Defense
power 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.
To meet the needs of varying military project specifications, Photonis Defense power
tubes come in a variety of sizes for airborne, mobile, and stationary design options.

REQUEST FOR INFORMATIONPower 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.
We highly recommend pairing one of our cavities with a recommended matching power tube and can
work with you to determine which power tube cavity your application requires.
