In some characteristic places, it needs to be applied to the signal jammer, mainly to shield the signal. Since the signal will appear at any time, the signal jammer should also be turned on at any time, but doing so is likely to cause the current to be unstable. The solution is to change the current size. So how to change the current size of the signal jammer? There are three main methods:1. Replace the resistor or power supply (voltage). In the circuit of the signal isolator, the magnitude of the current can be changed by means... more

For the radio frequency interference problem of GSM mobile phones, GSM mobile phones work in TDMA mode, and radio frequency transmission and reception are not carried out at the same time. The basic principle of reducing RF cell phone interference is to strengthen matching and isolation.In the design, considering that the transmitter is in a high-power transmission state, it is more likely to generate interference than the receiver, so it is necessary to ensure the matching of the power amplifier (PA). In addition, the isolation of t... more

A jammer is a very effective device for protecting yourself. When running, it scans from the low end to the high end of the front-end channel at a certain speed. This scanning speed will cause scrambling and interference to the message signal received by the mobile communication, and the mobile communication cannot detect the normal data sent by the base station, so the mobile communication cannot establish a connection with the base station. Mobile communication is manifested as network search, no signal, no service system, etc.Of c... more
