Do you know the mobile phone jammer composition principle ? In here, you will get the answer !

Mobile phone jammer, it is an instrument used to prevent cellular phones from receiving signals from base stations. When used, the jammer effectively disables cellular phones. These devices can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected.


Since cell phone signal jammer is capable of blocking all cell phones in a certain shielding range, what is inside the phone jammer? We are going to tell the internal construction of the cell phone jammer. Electronically speaking, cell phone jamming devices are basic electronic devices, which is much simpler than you think. Most of them have switches to activate jamming at different frequencies. They send signals by the antenna. On more advanced devices, antennas are external to provide longer range and may be tuned for individual frequencies. The main electronic components of a phone signal jamming blocker includes voltage-controlled oscillator, tuning circuit, noise generator, RF amplification.
