Cell phone signal jammer circuit diagram. For this purpose cellphone jammer circuit is used to block the signals received by the cell phones ceasing them to work properly. A mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones. These 3 circuits when combined together form an efficient cell phone jammer circuit.
Rf amplifier circuit comprises of the transistor q1 capacitors c4 c5 and resistor r1. A cell phone jammer we block the signal or destroy or add some noise in it that signal coming from the base station this is known as bad transmit ion so the cellular phone cannot transmit signal well. But it will be annoying when used at inappropriate places like hospitals schools theatres and so.
Basically a mobile jammer circuit is an rf transmitter which broadcasts radio signals in the same or similar frequency range of the gsm communication. The gsm1900 mobile phone network is used by usa canada and most of the countries in south america. The amplified signal is given to the antenna through capacitor c6.
The cell phone jammer works with the frequency of 450mhz if this frequency is hunk we need to generate the 450mhz frequency with same noise which is acted as a blocking signal because the receiver of the cell phone signal will not be able to understand the received signal. By this circuit we can able to block the cell phone signals. This circuit is very efficient to jam the signal of all signal bands of mobile communication.
How to make cell phone signal jammer in this article you will learn how to make a cell phone signal jammer using 555 timer with less number of components. A beautiful diy gsm jammer or mobile cell phone jammer schematic diagram for use only in gsm1900 with frequency from 1930 mhz to 1990 mhz.
