power tube cavities


Photonis Power Tube Cavities are a result of our extensive experience in RF engineering partnered with customer demand. For many years we have been designing and developing specialized circuitry for power tubes, generally termed as “cavities”. Our Power Tube cavities are complete RF circuits that are necessary to tune and operate a matching power tube. Each power tube cavity is designed to match a specific tube to produce a final high-power amplifier stage for a specific frequency band and service. Power Tube cavities are an essential part of installation and maintenance operations needed for Photonis Power Tubes. We recommend pairing one of our cavities with any recommended matching power tube. Photonis can provide cavities that cover frequency ranges of 140 to 1000 MHz and we can work with you to determine which power tube cavities you require to support and optimize your installation.
