Chinese Microwave System TPG1000Cs, Described in Peer-Reviewed Study, Sustains 20 Gigawatts for One Minute, Operates with Fifty Billionth of a Second Pulses and Raises Debate on Potential Impact on Low Earth Orbit Satellites
Chinese researchers reported the development of a compact microwave system capable of sustaining 20 gigawatts for an entire minute, according to a peer-reviewed article, highlighting the potential to interfere with low earth orbit satellites without the use of missiles.
China announced a breakthrough in high-power microwave technology with the description of the TPG1000Cs system, developed at the Northwest Institute of Nuclear Technology in Xi’an. The study was led by physicist Wang Gang and published in the journal High Power Laser and Particle Beams.
According to the article, the system is able to sustain 20 gigawatts of pulsed power for a full minute. This result represents a leap from previous microwave drivers, which operated for only a few seconds before overheating or depleting stored energy.

Geologists find traces of a continent that disappeared 155 million years ago after separating from Australia and reveal that it did not sink, but broke into fragments scattered across Southeast Asia.
The device is described as compact enough to be transported on a truck while maintaining high energy density. Many media outlets have begun referring to the system as a potential “Starlink killer,” although the study focuses on the pulsed power generator.
What Is a High-Power Microwave Weapon
A high-power microwave weapon uses intense bursts of radio energy to overload electronic components. The goal is not to physically penetrate targets but to interfere with or damage circuits from a distance.
Military planners value such systems for their ability to disable radars, communication links, or satellites without generating debris in orbit. This helps avoid clouds of fragments that could threaten other space equipment.
Chinese models indicate that a ground-based one-gigawatt system could disrupt or damage low earth orbit satellites. Starlink satellites orbit a few hundred kilometers above Earth, according to the material presented.
The Sinus7 driver from Russia is cited as a technical reference. It can operate for approximately one second, produce about one hundred microwave pulses, and weighs around ten tons, functioning in short bursts and laboratory environments.
How the TPG1000Cs Stores 20 Gigawatts of Compact Microwaves
The team focused on the pulsed power driver, responsible for storing electrical energy and releasing it in very short bursts to a microwave source. The TPG1000Cs relies on a Tesla-type transformer and a special dual-width pulse formation line.
Each pulse is shaped to about fifty billionths of a second, maintaining a flat and stable output. The design replaces standard insulating oil with Midel 7131, a liquid insulating material with high energy density.
The refined oil impregnation process reduces the formation of gas bubbles that could cause sparks. This allows for storing more energy in a smaller volume and improves reliability under high voltages.
Physically, the system measures about four meters long, one and a half meters wide and high, with a mass close to five tons. The casing uses an aluminum alloy to reduce total weight.
According to the authors, the equipment recorded about two hundred thousand pulses in repeated one-minute runs. In a single session, up to three thousand high-energy pulses were fired.
From Straight Tubes to the Compact Design Associated with Starlink
Previous high-power microwave generators utilized straight tubes for pulse formation. These long cylinders, filled with insulating oil and cables, made the systems bulky and difficult to install on mobile platforms.
In the TPG1000Cs, the layout has been replaced by a dual U-shaped structure. Energy circulates back and forth in a shorter encapsulation, maintaining the 20-gigawatt power with less occupied space.
With the new insulating liquid, the system achieves the same power level as older equipment, occupying about half the space and with reduced weight. The study points out that this advancement did not occur in isolation.
In 2024, the same group reported a repetitive fifteen-gigawatt generator in the journal Review of Scientific Instruments. The use of the same insulating oil indicates continuity in the compact pulsed energy research line.
Microwaves and the Focus on Satellite Constellations
The system gained attention for aligning with warnings from Chinese authorities about risks associated with SpaceX’s Starlink network. Military analysts in Beijing published studies on how to disrupt large satellite constellations.
High-power microwaves appear in these studies, alongside lasers and cyber tools. Starlink satellites play a visible role in Ukraine, maintaining communications and drones when ground networks fail.
For strategists considering scenarios involving Taiwan or other flashpoints, a ground-based microwave weapon capable of reaching low earth orbit is described as a relatively cheap alternative to disrupt support.
There is also a geometric aspect. Starlink has gradually lowered the altitude of its satellites to reduce collision and space debris risks. Shorter distances may make ground-based energy beams slightly more effective, as the signal disperses less.
What the Study Indicates for Space Security
Despite the label of “Starlink killer,” the TPG1000Cs is described as a laboratory pulsed power generator. There is no record of use against real satellites.
To become an operational system, it would be necessary to integrate the driver with a microwave source, directional antenna, and platform such as a truck, ship, aircraft, or satellite. The article does not describe this complete integration.
Independent analysts note that non-kinetic anti-satellite tools are more difficult to attribute than missile attacks. In this context, the new mechanism is seen as a technological advantage.
The Sinus7 from Russia and other drivers analyzed by the High Current Electronics Institute indicate that Moscow and Washington have been studying similar technologies for years. Still, the Chinese system combines high power, long firing times, and compact size.
For civilian users relying on satellite navigation, weather forecasting, and video transmission, the trend indicates greater involvement of space infrastructure in military competition. Devices like the TPG1000C reinforce that space has become a contested arena.
The main study was published in the journal High Power Laser and Particle Beams, detailing technical parameters, repeated testing, and construction characteristics of the system. The article describes the advancement as a significant step in the field of high-power pulsed microwaves.
É lamentável ver tantos desperdícios, tanto de tempo, como de recursos pra ver quem é o mais forte e tem mais poder! Um profeta escreveu a milhares de anos. Bem sei ó JEOVÁ, que não pertence ao homem o dirigir os seus passos. Nosso lindo planeta está sendo destruído de uma forma alarmante! Como necessitamos da vinda do Reino ou Governo de Deus com urgência, para resolver de uma vez por todas, todos os problemas da humanidade. Mateus 6:9,10
