H6 Systems Commercial Transmitters

H6 Systems provides transmitters for research, health care, and security applications. Our transmitters are high-power pulsed commercial transmitters with output powers that run from hundreds of kilowatts to well into the megawatt range. H6 Systems transmitters can be supplied as stand-alone systems, or they can be integrated into your existing equipment.

Continued operation of your system is critical; that's why all of our commercial transmitters include fault monitoring to protect your equipment against internal failures and harmful operator input. Your transmitter can be controlled from a laptop running our GUI, from a PLC, from a mechanical switch panel, or from your own computer with Modbus. Please note that higher-power units (above 1.5 MW) are liquid cooled, while lower power units are air cooled.

Our goal is to provide our customers with transmitters that deliver optimal performance and reliability. Take a look at a few of our transmitters at the bottom of this page to see how we can help meet your transmitter needs. For broader information on frequency and power ranges, take a look at our Tube Finder. We build around these tubes, which are available from third-party manufacturers. If you don’t see what you need, give us a call; not all tubes are listed. Additionally, if you need to achieve a specific field strength, take a look at our Field Strength Calculator. It will help you estimate the necessary tube power to generate your field.

Magnetrons (pulsed) — These vacuum tubes are oscillators (not amplifiers). They output high-power RF pulses when pulsed with high voltage. They also require a specific filament voltage and air or liquid cooling. Pulse widths are in the 1–4 uS range, with duties close to .001.

Klystrons (pulsed) —These vacuum tubes are amplifiers. They amplify RF pulses that occur within the timing of a high-voltage pulse. They require a specific filament voltage, as well as a solenoid voltage to focus the electron beam. They are usually liquid cooled. Pulse widths range from 4 uS to 1 mS. Duties range from .001 to .03.

CC TWT (pulsed) —These tubes are amplifiers. They amplify RF pulses that occur within the timing of a high-voltage pulse. They require numerous floating power supplies as well as air and liquid cooling.

Your transmitter can be controlled from a laptop running our GUI, a PLC, a mechanical switch panel or from your own computer programmed to communicate through ModBus.
