Generally mobile phone jammers use 5VDC to operate. 6 Most Common Smart Phone Users’ Security Mistakes, Tuning Circuit (to select desirable frequency to be jammed), Noise Source (commonly built-in in Tuning Circuit), RF Amplification Unit (so-called “gain stage”), GSM (850MHz and 1900MHz in America, 900MHz and 1800MHz in Europe), RFID (also known as UHF/VHF, 14MHz – 400MHz, 800MHz and 2450MHz). FUCK FUCK, dammit. RF Amplification Unit is what you need when you wish to increase the area covered by your jammer along with its signal blocking power. And you are welcome to become a part of it. Not to mention the 38 kHz signal that the remote control data is modulated on is no where near the 850 - 1200 MHz cellular bands.
