There are three types RF Jammers.

1. VCO(voltage controlled oscillator) Technology

Requirements for the jamming range is not high, extremely sensitive civilian consumption levels of low cost, and efficiencies are not very strict environment.

2. DDS (Direct Digital Synthesis)Technology

Requirements for the jammer need wideband frequency range, and select accurate frequency point, such as 20-3000MHz NO gap jammer.

3. Pseudo random digital Gaussian white noise technology.

Requirements for the jamming range is very high, low electromagnetic radiation, can accept high cost, using for national security and military, have strict requirements for jamming range.
