Offline . Increase the inductor capacitor circuit components value for increasing the frequency.”. Increase the frequency of tuned circuit by using this formula F= 1/ (2*pi*sqrt (L*C)). Can I make it? /Rect [ 90.24 473.84 504.24 499.76 ] Hi i'm not able to get 22nH in my place. RF amplifier feed is given through the capacitor C5 to the collector terminal before C6 for gain or like a boost signal to the tuned circuit signal. need coil specifications,as its gage,number of turns ,distance betewen the adjesent turns, hai,i am unni from kerala .i need a detailed design for each components for mini project, Pawan GSM/CDMA/3G signals have a frequency of 800-900MHz, 1800-1900MHz and 2100-2200MHz (last one is 3G). Then you shouldn’t be building this circuit…. Keep the VAR SWEEP control to CAL. This is very helpful for me. We do not intend to infringe any legitimate intellectual right, artistic rights or copyright. any other alternatives for bf494 transistor ..??? Keep it up. moreover i cant understand why that jammer circuit alone looks complicated where as the one in this page looks much simple.PLEASE HELP;i need a simple circuit of jammer that could work in india anyway thank u for ur effort in making that new page i relly got some good ideas, SIR!i still cant get it. Basically, a Mobile Jammer Circuit is an RF Transmitter, which broadcasts Radio Signals in the same (or similar) frequency range of … /Subject () Unless you like threats of large fines, be extremely careful where you use this if you live in the US. Multiply this by the Time/Div control and magnification: Time = Horizontal divisions X Time / Div (X (1/10) if X10 is used) Frequency measurements are made by measuring the time taken by one cycle, Frequency1/Time period. /CSpg /DeviceGray It works properly. this circuit works ??? What is the job of antenna, the signal is generated by the tuning circuit. Dunno if folks are aware but using this thing in at least the United States is hardcore illegal and can get you in serious trouble with the FCC (or CISPR if you live in Europe). sir kindly tell me the list of components i c’ant understand components on diagram, Dis works with the help of current. Network Jammer Circuit Diagram. Good post,thanks for the author sharing the news about the cell phone jammer,from my point of view ,the cell phone jammer will be become more and more popular. There we need a metal box to build this unit or system. F=1/2*pi√LC, i want rang of frequency upto 2100mhz so, which changes i have to do in this circuit, i dont know how to connect the antenna to the circuit. Hello, Thank you very much for your patience . can we take antennas from radio?............!! /CreationDate (D:20150801103004+03'00') we supply all kinds of mobile signal booster/repeater and jammer with high quality , pls feel free to visit our website http://www.asicon.net and http://www.dzxcon.com . [ 10 0 R 11 0 R ] The circuit diagram for the same is give below. >> i am from india i need to block signals from 900 to 1800 to make it work both for GSM and CDMA.. please help and is this yagi antenna relly nesasary, will u kindly snd me the equivalent circuit that work in india....my mail id-jishnu.jish93@gmail.com, Hiaswinth raj and jishnu NP I will send you a project i hope that work in india but wait few days because i am bzy at other project Best Regards, Can u please send circuit for 900 mhz mobile phone jammer. I definitely look forward to more useful post like this. i am working on this circuit for past 3 months. 5 0 obj nice explanation Saifullah and once again thanks for ur info.its more useful for me .keep it up........ hey thanks then i want to design electronic circuit so plz suggest me for how to design thanks, hey u said antina tsop-6 package isn't but i cant find out the model so send the part number of the antena or send the detail description about antena pls i make ur project it is success so i want to transmit and check the signal so plz, Dear mani part number is DG2001 The most important part of any transmitter is the antenna, so a suitable antenna should be selected, can u suggest what antena should be used to generate a frequency >800MHZ. Sir, 103 means 10 x 10*3 pf, or 10 x 1,000 pf. I tried creating the circuit. pls send me circuit and detail for project which work. Led Strip Light Kits Buy Online For making mobile jammer we need 555 integer circuit 8 pins for adding noise in transition. Learn how your comment data is processed. /Pattern << Mobile: 0086-13670292315, hello sir, stream Now, let us learn about one more interesting concept i.e. so you are engineer or google it and check the output of you circuit and by using Dipole length formula (antenna length ) September 2, 2018 By Administrator 133 Comments. If the circuit is not working, just increase the resistor and capacitors values in the circuit. Check your local laws before using such devices. Log in or register to Like and Comment . if we are intending do the same project in india..then which type of antenna should v use? is work in proteus but how can i confirm that is correctly work by proteus. So here in the above circuit, we generated the 450 MHz frequency to block the actual cell phone signal. We know that inductor is used to store magnetic energy. Raspberry Pi LCD Display Kits If yes how can I make it.. /A << VHF band uses 300-300MHz, and UHF band is a wide band with 300-3000MHz frequencies but as a rule microphones are not using high frequencies for their work. Digital Multimeter Kit Reviews So the transistor Q1, capacitors C4 & C5 and resistor R1 constitute the RF amplifier circuit. Sir please send me components list and ranges, used in the circuit. When the transistor Q1 is turned ON, the tuned circuit at the collector will get turned ON.
