i have the working circuit but when i give it to you, you have to be sending me message to direct you on it. You have entered an incorrect email address! We do not own the verification of the circuit.

However, the below mentioned formula can be used to calculate the required values. "compareAt": { },

The world of electronic gadgets is so big and interesting place! Such cell phones have their transmitted frequency always separated exactly by 45MHz from its received frequency.

can you send me it please [email protected], thanks , It will be very useful article me, The circuit is not working…..xo …..is their any alternativeeee to that, I need a exact circuit diagram of cell phone jammer circuit. = A platform for tech faculty and institutions, Enabling commerce between buyers & sellers of electronics in India, Everything you want to know about India's electronics industry, Enabling you to benefit from investments in technology, Self-Driving Electric Vehicle For Delivery, Make This Handy Zener Meter For Faster Testing, Open-Source Industrial SBC Powered By ARM Cortex-A5 SoC.

Pls say wat is meant by prototype . }

Also, you'll need a good RF-testing equipment, an aluminium box, ultra-high frequency connectors which can be found in old phones, 9-volt battery, and a voltage regulator. We can’t guarantee that the project would work but the concept is sound. Except for the feed back component, C5, all are almost identical. AC-DC and DC-DC adapters are made for almost all types of mobile signal jammers. Thanks.

This project highlights the design of a simple, low-cost mobile-phone- jammer and aims to present a solution for the problem of inappropriate-use of the cell-phones in restricted and prohibited-areas.
