My guess is that most of us can help you. But, "should we help you" is question.

Asking for circuit diagrams for "Engineers Day"? Engineers typically design things, not copy others work! You are not likely to get many responses because those things are illegal over here. Not that they don't exist, you just can't buy one at Radio Shack.

That said, it isn't that hard to do. Park some energy (much more that what the mobile phone will be receiving) on the frequency you want to jam. Add a little biphase modulation to spread it around. Use a VCO with a triangle wave driving it to cover wider bandwidths.

Design one yourself and then improve it. Then, the next time someone asks for a mobile jammer, YOU can be the one to send your diagrams.

What is it with people from india and mobile jammers?

I mean, if there is the word "mobile" and the word "jammer", in a message, you all appear like pre-programmed drones asking for schematics.

I would sincerely like to understand your specific interest.

Have you ever heard an Indian guy talk on a cell phone? Times that buy a billion.

It ain't pretty.

Please give me my mobile jammer!

By the way I do not want to fall into ethnophobic content, and that was not my intent.

But it is still strange this "extreeeeeeeme" interest in schematic of mobxle jxmmer.

I mean, no interest in filters, pll, amplifiers, signal theory, but just in already cooked results in the form of a schematic in regards to mxbile jaxmer.

I am deliberately corrupting the forbiden words, to avoid activating more drones.

The best way to do a phone jammer is to walk to the person using the phone you want to jam and jam it in his mouth. No schematic diagram needed.

Excellent response!!! Any coward can hide in the bushes and push a button, but the real hero will confront the offender(s) directly. It is the only way to effectively deal with bullies of any sort.
