Voltage Regulator Power Tubes

Power Tubes with coaxial construction designed to be used as voltage regulators in airborne and fixed station equipment.

Sturdy, coaxial construction
Minimized tube inductance
Efficient and effective cooling
Withstands severe environmental conditions
Dependable performance under heavy vibration


Photonis Defense offers voltage regulators for use in airborne and fixed station equipment. Designed to be sturdy the voltage regulators feature a coaxial construction that minimizes tube inductances and increases system reliability. The plate characteristics of the tubes have been specifically controlled to provide the highest transconductance desirable in a series regulator service.  The construction of the voltage regulator also allows for efficient and effective cooling, by either forced air or immersion. Photonis’ voltage regulators have been engineered to withstand severe environments and have a proven track record of dependable performance even under severe vibration.

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. Please contact us for more information.
