High-Power RF Transmitters
and High-Voltage Modulators

H6 Systems Inc. is a manufacturer of tube-based, high-power RF transmitters and high-voltage modulators used in 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 powers well into the multi-megawatt range.

We integrate our own modulators with vacuum tubes, cavities, PLCs, fault systems, cooling equipment, antennas, positioners, and enclosures to produce high-power transmitters that meet your specifications. Feel free to use our Tube Finder or Field Strength Calculator here on our website to get started, or design a complete custom RF system with our Custom RF System Builder and request a quote from our engineers on your build.
