History
GREETWIN Technology was founded in 2014, has been committed to the sale of high-quality RF Jammer. At the beginning, GREETWIN provided with mobile phone jammer for Examination and meeting room, and high power jammer for prison. Our engineers custom design many solutions for the security industry. With backgrounds in RF engineering, signal analysis, and mechanical engineering, our engineers and technicians design and manufacture advanced jamming technologies.
Such as, High power bomb jamming devices, Military IED jammers, programable DDS jammer, VIP Convoy Bomb Jammers (RCIED Jammers), Mobile Phone Signal Jammers, Prison Jammers, Portable Jammers, Handheld Jammers, Drone jammer, Digital jammers.
There Are Three Types RF Jammers
We focus on digital Gaussian white noise technology. After 12 years development, GREETWIN has became the leader supplier of RF Jammer in the global market.
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.
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.
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.
