What does a DDS jammer do?

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?

With our DDS jammers, operators can prevent radio receivers from capturing RCIED blast commands as well as radio communications used by enemy forces. RCIED stands for Remote Controlled Improvised Explosive Device.

The DDS jammer is built into the carrying case and uses a proprietary PLL stabilization component design. This design reduces heat while its characteristics retain a secure medium to transmit its jamming signal without degradation.

What is the application scenario of DDS jammer?

Generate local oscillator clock - the simplest application is NCO (Numerically Controlled Oscillator), that is, to generate a single-frequency sine wave signal. If combined with a digital mixer, the operation of up-conversion and down-frequency can be completed in the digital field. The center frequency is shifted;

Generate signal source - theoretically any signal, including modulation signal, the phase can be continuous when the frequency is switched, and the precision of frequency adjustment can be made very high; the adjustment of parameters such as signal amplitude and DC offset can also be realized in the digital domain, greatly Simplify the design of peripheral circuits;

Measure the characteristics of the circuit - generate the excitation signal source, provide excitation for the measured object, compare the changes of the parameters such as the amplitude/phase of the measured signal and the excitation signal, analyze the characteristics of the measured signal, the frequency switching of DDS is flexible, and the phase is continuous , and supplemented by the advantages of DSP, more and more analysis functions can be realized in the digital field;

It is used to generate digital modulation in communication - and can easily obtain signals of different frequency bands by using the principle of spectral aliasing. For example, a DAC using 100Msps can obtain a 120MHz modulation signal through a simple band-pass filter without the need for an analog upper frequency conversion;

The power supply is used for the generation of the SPWM signal - the principle is also DDS, but the analog voltage signal is obtained by using PWM as a DAC

What are the characteristics of a DDS jammer?

The DDS jammer is not only a bomb jammer, but also a high power portable DDS escort jamming system, portable RF jammer, and portable bomb jammer. The jammer enables the most effective and reliable RF jamming technology and is equipped with a fully integrated broadband jamming system.

The DDS jammer can continuously and simultaneously cover all RF communication frequencies between 20MHz and 3600MHz.
