CA3130 is opamp! by simple loop can detect any frequency from 50HZ to 1.2Ghz. the output over NPN transistor bc548 will connect to 555, pin2... it mean when frequency come to OPAMP the stability will change and signal goes to 555 and buzzer will biiiiiiiiiiiiiizzzzzzzzzzzzzing and LED blinking! this project is SMD version of mobile phone detector, if need Schematic or Diagram let me know.........
