High Voltage Modulators

H6 Systems Inc. is a manufacturer of tube-based, high-power pulsed RF transmitters and high voltage modulators used for susceptibility testing, weather radar, health care, research, and security systems

In business since 1980, our company builds systems based on magnetrons, klystrons, tetrodes, triodes, and TWTs with frequencies ranging from 150 MHz to 40 GHz and power into the multi-megawatt range.

We integrate tubes, cavities, PLCs, fault systems, cooling equipment, antennas, positioners, enclosures, and our own modulators to produce high-power transmitters.
