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.

​Anti-Drone UAV Jammer uses Radio frequency wireless wireless electromagnetic wave co-channel interference technology to interfere with drones. Interference shielding can be performed for all positioning signals. Anti-Drone UAV Jammer is a directional gun jammer, mainly for mandatory control of drones or flight models in flight, cutting off the connection between drones and remote controllers at a long distance The aircraft is forced to return or make a forced landing to ensure the safety of the low-altitude airspace in the area.

Cell Phone Signal Boosters use the backward antenna to receive the mobile station's uplink signal at the same time, and it is processed by the uplink amplification link along the opposite path: that is, through the low noise amplifier, downconverter, filter, intermediate amplifier, upconverter, power amplifier and then transmitted to the base station. Thereby, two-way communication between the base station and the mobile station is achieved.
