Hundreds of radar systems in operation today utilize tetrodes or thyratron/PFNs for high pulse repetition frequency pulse modulation. These vacuum tube modulators are expensive to maintain, and their relatively short lifetimes constitute a significant operational expense.

DTI's solid-state, high voltage switches work as high-power cathode modulators for klystrons, CFAs or magnetrons, and as low-power modulators for tubes that use modulating anodes, grids, or control electrodes. PowerMod™ switches are perfect for retrofits, test sets and new designs. A transmitter upgrade using modern, solid-state technology may be the most cost-effective answer to problems of high failure rates and lengthy repair procedures common to transmitters that incorporate vacuum switch tubes. A retrofit may encompass a few components or a complete subsystem. DTI's high-efficiency modulators are inherently pulse-width agile, and can open in less than a microsecond, often eliminating the need for a conventional crowbar. We have upgraded radar transmitters across a wide range of applications.
