What is the use value of DDS Jammer?

​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.

How does a DDS Jammer work?

​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.

What are the features of DDS Jammer?

​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.

What do you know about DDS Jammer?

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.
