gsm jammer circuit diagram

I m working on my project on the contruction of downlink GSM jammer for
DCS (1800Mhz).
kindly guide me for the purpose & i need the required Circuit diagrams for its construction
thanks.

I grow tired of such request ... This forum is intented to form a professional community that helps each other working on honorable design problems. It should not serve any unethic or immoral goals. If not why wouldn't we write a manual on the forum how to make self-made bombs? With schematics attached of course! Bullocks!

u r doing a project without any circuit & information?
U want others to do it 4 u?
what u will do then?

y can use the diode to produce a wideband noise and then use the active filter to select a fit band, then amplifier it, this is the simplest noise jamer,good luck!
