* PIN CONFIGURATION OF IC
How the circuit works?
- Ordinary LC (Coil-Capacitor) circuits are used to detect low frequency radiation in the AM and FM bands.
- The tuned tank circuit having a coil and a variable capacitor retrieve the signal from the carrier wave.
- But such LC circuits cannot detect high frequency waves near the microwave region.
- Hence in the circuit, a capacitor is used to detect RF from mobile phone considering that, a capacitor can store energy even from an outside source and oscillate like LC circuit.
