A wide variety of power tubes and their associated circuitry components all designed for specialty use

Voltage Regulator Power Tubes

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 Defense voltage regulators have been engineered to withstand harsh 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.

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.
