Pin On Electronic Circuit Diagrams
A Motorola cellular phone had distinct signals in the range of 240MHz and 400MHz.
. A study carried out by Pacific Northwest National Laboratory for the United States Department of Energy on cell phone detection using this technique showed that different phones propagated using different frequency ranges. Venugopal 09881A04A8 Under the Esteemed. So a circuit detecting gigahertz signals is required for a cell phone detector.
A Project Report at CELL PHONE DETECTOR Department of Electronics Engineering Session 2012-2013 ACKNOWLEDGEMENT. Cell Phone Detector Project Report. About the CA3130.

CELL PHONE DETECTOR TO PREVENT UNAUTHORIZED USE IN PROHIBTED AREAS Group members Id no. An ordinary RF detector using tuned LC circuits is not suitable for detecting signals in the GHz frequency band used in mobile phones. CA3130 and CA3130A are op-amps Operational amplifiers that combine the advantage of both CMOS and bipolar transistors.
Its small size makes it handy and it easily occupy space in your pocket. An LG cellular phone had distinctive signals from 260MHz to 300MHz. Gate-protected P-Channel MOSFET PMOS transistors are used in the input circuit to provide very-high-input impedance very-low-input current and exceptional speed performance.
The lead length of the capacitor is fied as. During this project individuals will be introduced to a circuit that contains transistors capacitors resistors light-emitting diodes as well as a CA3130 IC. A short summary of this paper.
