Handheld Cell Phone Blocker 16 Bands 5G Jammer

Define Signal blocker Jamming

The interference of all unwanted signals with the same frequency as the useful signal that falls within the passband of the receiver, also known as co-channel interference. These useless signals, like useful signals, are amplified in the receiver and converted to frequency to fall within the intermediate frequency passband. Therefore, as long as there is co-channel interference at the receiver input, the receiving system cannot filter and suppress it.

When two or more different frequency signals act on a nonlinear circuit, the signal jammer will modulate each other to generate a new frequency signal output. If the frequency falls within the receiver's working channel bandwidth, it will interfere with the receiver.
