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.

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.
