allisonburtch / log_jammer

This is a schematic for a cell phone jammer that works for the frequency band GSM 1900. It was part of my master's thesis at ITP/NYU. See website for details.

Hi there. I found this cell phone jammer on the internet. It is for the GSM 1900 spectrum. Many of these parts are legacy and I had to figure out replacements. If you look at the actual schematic in Eagle, I've noted the new name of each part. Feel free to email me with questions: allison//at//allisonburtch.net

Schematic in Eagle of triangle wave generator, voltage inverter and noise generator. Schematic of the VCO and rf amplifier leading to antenna.

This is the board layout of the rf part in Eagle.
