The Op-amp part of the circuit acts as the RF Signal Detector while Transistor part of the circuit act as the indicator. The first circuit of the cell phone detector is a simple implementation using an Op-amp and a few other passive components. This low power signal can be amplified and used to power any indicator like an LED in this case.Īlso Read the Post: Mobile Phone Jammer Circuit Circuit 1: Simple Cell Phone Detector Circuit This signal is rectified by the Schottky diode. When an inductor is placed near the RF signal source, it receives the signal through mutual induction. In the Schottky diode circuit, the Schottky Diode is used to detect the cell phone signal as they have a unique property of being able to rectify low frequency signals, with low noise rate. The basic principle behind the Cell Phone Detector circuits is to detect the RF Signals.
