Photonis Defense's Power Tubes can be found across the globe, from mobile communications applications to physics research and were designed to meet very stringent environmental and technical specifications. With over 70 years of design and manufacturing experience, through our RCA & BURLE heritage, Photonis Defense has established a reputation for superior product performance, outstanding quality, and long operating life. The power tube product line encompasses a wide variety of tubes and their associated circuitry components all designed for specialty use. Photonis’ power tubes can also be purchased with specialized circuitry, generally termed cavities, which are the complete RF circuits necessary to tune and operate a matching power tube. These gridded power tubes, both tetrodes and triodes, can be used in defense, communications, broadcast, research and a variety of other applications requiring RF amplification or generation. Photonis engineers continue to add innovative tubes and associated circuit designs for new applications, however, they can also design a custom power tube to meet a specific need.
