​DDS Jammer is a special device used to prevent illegal flying objects from causing harm to ground personnel and vehicles, and to protect the safety of people's lives and property.

​A DDS Jammer is a method of generating an analog waveform (typically a sine wave) by generating a time-varying signal in digital form and then performing a digital-to-analog conversion. Because operation within a DDS device is primarily digital, it provides fast switching between output frequencies, fine frequency resolution, and operation over a wide range of frequencies. With advances in design and process technology, today's DDS devices are very compact and low power.

​DDS Jammer isolation range: radius 100-500 meters (under -75dBm field strength, determined by the distance and signal strength from the signal base station in the open area) Transmission power: Integrated equipment ≥ 1000W, each frequency band ≥ 100W.

High-speed DDS Jammer composed of FPGA + R2R resistor network. Under the circumstance that component procurement is difficult and the price is high today, 20 to 24 resistors are a very cost-effective high-speed DAC solution. It should be noted that the wiring delay from the parallel data bus of the FPGA to each resistor node, Resistors should be selected with relatively high accuracy, such as at least 1% accuracy.

The DDS jammer represents a direct digital synthesis method for jamming signals in an RF jammer architecture. DDS jammers are dual application electronic warfare systems. They can be used to counter roadside bombs as well as to attack enemy radio communications.What does a DDS jammer do?What is the

Anti-Drone UAV Jammer is a series of activities specially developed for drones to cut off the communication signal between drones and flight control personnel to organize flight control personnel to use drones to commit crimes or hinder social and public safety.

Terrorists use drones to carry bombs, viruses, biological weapons against justice. Using drones to conduct thorough investigations and challenge legitimate national law enforcement agencies and military security, Anti-Drone UAV Jammer can jam the signals emitted by drones, and conduct complete and effective defense and interception of drones!

​Anti-Drone UAV Jammer mainly suppresses the drone signal by transmitting 900M 1.2G 2.4G 5.8G high-power interference frequency band, so that the drone cannot obtain GPS/Beidou positioning signals, and the control between colleagues and the controller The signal and image transmission signal are interrupted, so as to achieve the purpose of forced landing or return.
