Simple Mobile Signal Detector
Detector circuitA conventional RF detector using an LC circuit is not suitable for detecting signals in a band GHz frequency used in mobile phones.The transmission frequency of mobile phones is from 0.9 to 3 GHz with a wavelength of 3.3 to 10 cm. Here the circuit uses a 22p (C3) disk capacitor to capture radio signals from a mobile phone. The length of the antenna wire of the capacitor is fixed as 18 mm in 8 mm steps between the terminals to obtain the desired frequency. The capacitor, together with the antenna, acts as a small gigahertz gamma antenna for collecting radio signals from a mobile phone.
Assembling the Cell Phone Signal DetectorI assembled the detector on the printed circuit board. Pre-drew, pickled, zaludil and drilled.In general, everything is as it should be.
