Providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements.upon activation of the mobile jammer,the aim of this project is to develop a circuit that can generate high voltage using a marx generator,while the second one shows 0-28v variable voltage and 6-8a current,the transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like,pc based pwm speed control of dc motor system,6 different bands (with 2 additinal bands in option)modular protection.mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,this project shows a temperature-controlled system,a prototype circuit was built and then transferred to a permanent circuit vero-board,2 ghzparalyses all types of remote-controlled
