The purpose of the wifi jammer is to isolate, and the circuits that are easy to interfere with each other can be considered isolated:
1) For example, the radio frequency unit and the intermediate frequency unit, the intermediate frequency signal of the receiving channel will cause a great interference to the radio frequency signal; on the other hand, the radio frequency signal of the transmitting channel will also cause radiation interference to the intermediate frequency signal.
2) For example, the local oscillator circuit in the radio frequency area should be shielded separately. We know that the local oscillator level itself is relatively high, which will cause greater radiation interference to other units.
3) For example, the digital signal processing circuit is a strong radiation source, and the steep upper and lower edges of the high-speed digital signal will interfere with the analog radio frequency signal.
4) For example, in a cascaded amplifier circuit, the total gain may exceed the spatial isolation between the output and the input, so that one of the oscillation conditions is satisfied, and the circuit may self-excite.
