PURPOSE: An electric wave generating apparatus for jamming is provided to generate a jamming electric wave offsetting a frequency of band assigned and received by a mobile communication apparatus from a base at a place where requires silence or electric equipments, which are sensitive to electric wave, are set up, thereby maintaining a stable atmosphere at those places. CONSTITUTION: The electric wave generating apparatus for jamming comprises: a transformer(10) falling an input common power into a predetermined voltage by an established winding ratio; a power processing mean(20) rectifying and stabilizing the voltage of the transformer(10) and supplying to the circuits as a useful voltage and current; an oscillating control mean(30) oscillating by varying supplied operation power, oscillating with a cycle of 240 microsecond at a central frequency of the operation power, thereby controlling a frequency oscillating operation; an oscillating mean(40) oscillating the frequency group having a same band with transmitting-receiving frequency band assigned to mobile communication apparatus according to the control operation of the oscillating control mean(30); a mixing mean(50) converting the oscillated frequency group into an electric wave and generating the electric wave; and antennas(ANT1,ANT2,ANT3) transmitting the electric wave applied by the mixing mean(50) to the air. |
