UHF Mobile Tubes

Photonis Defense’s UHF or Ultra High-Frequency Mobile Power Tubes are small and compact for use in a variety of mobile applications where having a sturdy, efficient, and reliable UHF amplification source is essential. The UHF Mobile tubes are of ceramic-metal construction to provide enough strength and close tolerance in high-temperature operations. Even in these high-temperature environments, Photonis’ UHF Mobile tubes still manage to have a reliable, low-temp operation due to their forced-air-cooled design. Photonis’ tubes are also tested for durability and have a proven track record of dependable performance under severe shock and vibration. The UHF Mobile tubes are largely used as RF and pulsed RF amplifiers in compact aircraft, mobile and stationary equipment. They are designed to meet the low noise requirements of numerous applications and withstand stringent environmental conditions in unpressurized, airborne communication services. Many of Photonis’ UHF Mobile tubes can also be used as regulators or in distributed amplifier service.

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.
