The frequency band of the wireless call terminal is 160MHz to 170MHz, 320MHz to 330MHz, the configuration and operation is made.

The module signal output from the analog signal generator 430 of the analog module signal generator 400 is applied to the noise signal generator 110 to provide a resistor R1. Is supplied to the varicap diode (varactor diode) (D1) (D2), the capacitance of the varicap diode (varactor diode) (D1) (D2) changes according to the magnitude of the input and voltage. do. In FIG. 1, the varicap diode (varactor diode) D1, (D2), capacitor C1, inductor L1, capacitor C12, C8, C10, C2, C3 and transistor Q1. The circuit consists of a basic Colpitts oscillation circuit, the oscillation frequency of which is the capacitance of the inductor (L1) and the varcap diode (varactor diode) (D1) (D2) and the capacitor (C1) (C12) (C8). It is determined by the combined capacitance of C10, C2, and C3, and its frequency is oscillated in the noble circuit of transistor Q1. In this case, the resistors R3 and R2 supply an operating current for the transistor Q1 to operate.

The initial oscillation frequency is configured to be 160MHz, and the voltage having an analog continuity of 0V to + 5V, which is an output signal of the analog signal generator 430 of the analog module signal generator 400, has a varicap diode (varactor). When applied to the diodes D1 and D2, a capacitance corresponding to the applied voltage value is generated, and accordingly, the varicap diode (varactor diode) D1 and D2 according to the change of the applied voltage value. The capacitance of is also changed accordingly, and thus the frequency generated by the transistor Q1 is changed. That is, according to the voltage applied to the varicap diodes (varactor diodes) D1 and D2, the transistor Q1 generates frequencies reciprocating rapidly between 160 MHz and 170 MHz and between 170 MHz and 160 MHz. The received frequency becomes a noise signal for the radio calling signal of the radio calling terminal of 160MHz to 170MHz, so that the radio frequency of the radio calling terminal receiving radio signal operating in this band is interrupted. In addition, since a signal corresponding to an integer multiple of 160 MHz to 170 MHz is generated together in the circuit of the transistor Q1, a noise signal of 320 MHz to 340 MHz is also generated. Therefore, if 160 MHz occurs initially in transistor Q1, a 320 MHz signal is generated accordingly. Therefore, fast from 320 MHz to 340 MHz, and 340 MHz to 320 MHz, depending on the input signal voltage to the varicap diode (varactor diode) D1 (D2). A round trip signal is also generated at the speed, thereby interfering with the reception of the radio calling terminal reception radio signal operating at 320 MHz to 330 MHz in this band.

Since the noise signal generated here is low power, it is amplified into a sufficiently large signal by the noise signal amplifier 120. The signals of the 160MHz to 170MHz band and the 320MHz to 340MHz band generated by the transistor Q1 are blocked via the capacitor C11 so that the DC voltage is cut off and only the noise signal component is input to the transistor Q2. This transistor Q2 is a conventional amplification circuit, and the resistor R4 supplies an operating current for the transistor Q2 to operate. In the inductor L3 and the capacitor C9, a resonance phenomenon occurs from 160 MHz to 170 MHz. Select and amplify the band and the signals in the band from 320MHz to 340MHz. The signal amplified by the transistor Q2 is again supplied to the amplifying circuit of the transistor Q3 via the capacitor C4, where the resistor R5 serves to supply the operating power of the transistor Q3. The power input to the transistor Q3 is amplified by the transistor Q3, and then a noise signal in the band from 160 MHz to 170 MHz and from 320 MHz to 340 MHz by the impedance matching circuit of the inductor L2 and the capacitor C13. Is amplified and transmitted as noise propagation through the antenna unit 130.

Is supplied to the varicap diode (varactor diode) D3. The circuit composed of the varicap diode (varactor diode) D3, the capacitor C14, the inductor L6, the capacitors C26 (C15) (C24) and the transistor Q4 is a basic Colpitts oscillation circuit. The oscillation frequency is determined by the capacitance value of the inductor L6 and the varicap diode (varactor diode) D3, and the combined capacitance of the capacitors C14, C26, C15 and C24. The frequency is oscillated in the positive feedback circuit of transistor Q4. In this case, the resistors R10 and R7 supply the operating current for the transistor Q4 to operate.

The initial oscillation frequency is configured to be 869 MHz, and the voltage having an analog continuity of 0 V to +5 V, which is an output signal of the analog signal generator 430 of the analog module signal generator 400, has a varicap diode (varactor). When applied to the diode (D3), a capacitance corresponding to the applied voltage value is generated, and the capacitance of the varicap diode (varactor diode) D3 is changed according to the applied voltage value, This changed capacitance (capacitance) generates a noise signal that quickly round trips between 869MHz to 894MHz, and 894MHz to 869MHz, and the mobile phone terminal (cellphone) reception radio waves also exist in this band, so in the transistor Q4 The generated noise signal acts as a signal that disturbs the reception radio wave of the mobile telephone terminal (cell phone).

Since the noise signal generated here is a small power, it is amplified into a sufficiently large signal by the noise signal amplifier 220. The noise signal generated by the transistor Q4 passes through the capacitor C27, and the direct current (DC) voltage is cut off, and only the noise signal component is input to the transistor Q5. The transistor Q5 amplifies the input signal, and the resistor R8 supplies the operating current for the transistor Q5 to operate, and the resistor R17 and the capacitor C23 have a large power supply. It is configured for the protection of the transistor Q5, and the inductor L7 and the capacitor C25 are used for impedance matching of the circuit to the noise signal of 869 MHz to 894 MHz.

The inductor L9 has an impedance between the antenna ANT2 and the transistor Q7. Used for matching.

The module signal output from the analog signal generator 430 of the analog module signal generator 400 is applied to the noise signal generator 310 and is a resistor R20. Is supplied to the varicap diode (varactor diode) D4. The circuit composed of the varicap diode (varactor diode) D4, the capacitor C38, the inductor L13, and the transistor Q8 is a basic Colpitts oscillation circuit, and the oscillation frequency is the inductor L13 and the varicap It is determined by the capacitance value of the diode (varactor diode) D4 and the synthesized capacitance of the capacitor C38, and the frequency thereof is oscillated in the positive feedback circuit of the transistor Q8. In this case, the resistors R21 and R18 supply an operating current for the transistor Q8 to operate.

The initial oscillation frequency is configured to be 1840MHz, and the voltage having an analog continuity of 0V to + 5V, which is an output signal of the analog signal generator 430 of the analog module signal generator 400, is a varicap diode (varactor). When applied to the diode (D4), a capacitance corresponding to the applied voltage value is generated, and the capacitance of the varicap diode (varactor diode) D4 is changed according to the applied voltage value, Due to this changed capacitance, a noise signal is rapidly generated from 1840 MHz to 1870 MHz and from 1870 MHz to 1840 MHz, and the received signal propagation of the PC terminal is also present in this band, so that the transistor Q8 The generated noise signal acts as a signal that disturbs the reception of the PCS terminal.

Since the noise signal generated here is a small power, it is amplified into a sufficiently large signal by the noise signal amplifier 320. The noise signal generated by the transistor Q8 passes through the capacitor C37, and the direct current (DC) voltage is cut off, and only the noise signal component is input to the transistor Q9. The transistor Q9 serves to amplify the input signal, and the resistor R19 is configured to supply an operating current for the transistor Q9 to operate, and the resistor R28 and the capacitor C34 are large. It is configured to protect the transistor Q9 against power, and the inductor L12 and the capacitor C35 are used for impedance matching of the circuit to the noise signal of 1840MHz to 1870MHz. The signal amplified by the transistor Q9 is outputted, and then only the noise signal component is inputted to the transistor Q10 through the capacitor C35, and this transistor Q10 serves to amplify the input signal. The resistor R24 supplies the operating current of the transistor Q10, and the resistor R27 and the capacitor C33 are configured to protect the transistor Q10 against large power, and the inductor L10 and the capacitor ( C36) is used for impedance matching of the circuit to the frequency used. The noise signal amplified by the transistor Q10 passes through the capacitor C36 again and is input to the transistor Q11 to perform final power amplification again. The resistor R25 serves to supply an operating current for the transistor Q11 to operate, and the resistor R26 and the capacitor C32 are configured to protect the transistor Q11 against a large power signal. Inductor L11 is used for impedance matching. The signal finally amplified by the transistor Q11 is supplied to the antenna ANT3 of the antenna unit 330 and transmitted.

As illustrated in FIG. 4, the analog module signal generator 400 includes a digital signal generator 410, a random digital signal generator 420, and an analog signal generator 430. The configuration and operation are as follows, as shown in FIGS. 4 and 6.

The digital signal generator 410 is an oscillator, which includes a NOT gate and a crystal oscillator Y2 (22 MHz), capacitors, and a high-speed C-MOS (HC-MOS) (U3A) 74HC04. It consists of a NOT gate of HC-MOS (U3B) 74HC04, and the high-speed Sea-MOS (U-MOS) (U3A) 74HC04 and (U3B) 74HC04 are one high-speed Sea-MOS It is configured as some of the six NOT gate elements embedded in the (HC-MOS) 74HC04.

In the NOT gate, the crystal oscillator Y2 (22 MHz), and the capacitors of the high speed HC-MOS (U3A) 74HC04 of the oscillator, first power is supplied, + 5V or 0V is output from pin 2 of UMOS (U3A) (74HC04), and this signal is again returned through the high speed HC-MOS (U3A) through a crystal oscillator (Y2) (22 MHz). Feedback is made to pin 1 of 74HC04. At this time, since the crystal oscillator Y2 passes only its own frequency, the high speed C-MOS (U3A) 74HC04 generates a 22 MHz signal, which is a high speed C-MOS (HC-MOS). As the output of pin 2 of pin (U3A) 74HC04, it is input to pin 3 of pin (HC3) (U3B) 74HC04. The high speed HC-MOS (U3B) 74HC04 inverts the input signal and outputs it, and acts as a buffer for the signal. Accordingly, a digital signal having a constant square wave of a high voltage and a low voltage is output to pin 4 of the high speed HC-MOS U3B 74HC04.

The random digital signal generator 420 may include a shift register for shifting a signal from the digital signal generator 410 according to the input of a clock signal, and the shift register. It is composed of digital gate circuits for inputting the output signal of the register and converting the signal.

The output of pin 4 of fast HC-MOS (U3B) 74HC04 is again input to pin 8 of fast HC-MOS (U4) 74HC164. This high speed HC-MOS (U4) U74 (74HC164) is an 8-bit parallel-out shift register. That is, the signal input to pin 1 of the high speed C-MOS (U-MOS) U4 (74HC164) is transferred to pin 8 of the high-speed C-MOS (U4) 74C164. Pin 3, pin 4, pin 5, and pin 6, which are outputs of the high speed HC-MOS (U4) and 74HC164, using the input signal as a reference clock signal. (pin6), pin10 (pin10), pin11 (pin11), pin12 (pin12), and pin13 (pin13) are sequentially shifted, and among the outputs, pin10 and pin12 are output. ) Is input to pin 1 and pin 2 of the high speed HC-MOS (U5A) 74HC86 to generate a random digital signal. The output signal generated at pin 3 of the high speed HC-MOS (U5A) (74HC86) is again pin 1 (pin1) of the high speed HC-MOS (U4) (74HC164). Low feedback, the high-speed HC-MOS (U4) U4 (74HC164) continues to generate a random digital signal based on the input clock signal. The signal output from pin 3 of the high speed HC-MOS (U5A) (74HC86) is input again to pin 5 of the high speed C-MOS (U3C) (74HC04). The inverted signal is output to pin 6, which acts as a buffer for the signal.

In this random digital signal generated, the signals '1' and '0' randomly change as in the display digital signal of FIG.

The high speed C-MOS (U3C) 74HC04 uses some of the six NOT gate devices embedded in the one high speed C-MOS 74HC04.

The analog signal generator 430 includes a resistor R32, a capacitor C45, and a resistor R33. By the configuration of the resistor R32, the capacitor C45, and the resistor R33, a random digital signal output to pin 6 of the high-speed Sea-MOS (HC-MOS) (U3C) 74HC04 is generated. The voltage equal to the high voltage (+ 5V) of the digital signal is set to the upper limit voltage (+ 5V), and the voltage equal to the low voltage (OV) of the digital signal is set to the lower limit. Voltage OV and the upper limit voltage (+ 5V) as the high voltage (+ 5V) of the digital signal changes to the low voltage (0V) of the digital signal. This analog continuous voltage changes to reach the lower limit voltage OV, and the low voltage OV of the digital signal is equal to the high voltage of the digital signal. 5V), the lower limit voltage (0V) is an analog continuous voltage that reaches the upper limit voltage (+ 5V) in analog continuous mode. Change to arc

This analog signal is the same as the analog module signal shown in Fig. 6 (2), which corresponds to the random digital signal shown in Fig. 6 (1).

The remote control infrared signal receiving means IR RX (IR1) receives an infrared signal transmitted from the remote control, converts the received signal into a digital signal consisting of 1 and 0, and outputs the digital signal. It is input to the processor U1.

The power supply unit 600 supplies DC power. In the embodiment, DC 10V is supplied.

The configuration and operation of the microprocessor unit 510 and the mobile communication terminal jammer transmission control unit 500 are as follows.

After the power is applied, it takes some time to reach a steady state (+ 5V), at which time the microprocessor U1 may be abnormally operated. In order to prevent this, components such as a diode D5, resistors R30, R29, and capacitor C41 are added to pin 4 of the microprocessor U1. That is, the microprocessor U1 is designed to operate only when +5 V is supplied to pin 4 of the microprocessor U1 in the program, and a voltage is applied to the capacitor C41 through the resistor R30 during initial power supply. The charge begins to be charged, and this voltage is connected to pin 4 of the microprocessor U1 through a resistor R29, and when the state reaches +5 V, the microprocessor U1 senses and operates the voltage. To start. When the power is turned off, the voltage charged in the capacitor C41 is quickly discharged through the diode D5.

When power is first supplied, an operating reference frequency is generated at a crystal oscillator Y1 of 4 MHz, and the microprocessor U1 is operated based on this signal, and a signal output from the remote control infrared signal receiving means IR1 is generated. It is input to pin 18 of the microprocessor U1, and this signal is interpreted according to an internal program. According to this interpreted signal, pin 1 of the microprocessor UI outputs a voltage of 0 V or +5 V, and the field effect transistor FET Q12 is turned on or off by this voltage. OFF).

That is, when 0 V is output from the pin 1, the field effect transistor (FET) Q12 is turned off, and accordingly, the transistor Q13 is turned off, thereby driving the drive power control unit. Power supply to 520 is cut off.

When + 5V is output from the pin 1, the field effect transistor (FET) Q12 is turned on, thereby causing the field effect transistor (FET) Q12 to conduct current. This current causes the transistor Q13 to operate through a current through the base of the transistor Q13, and enters a state in which power can be supplied to the driving power control unit 520.

In the state in which the transistor Q13 is ON, the microprocessor U1 uses the output voltages of the pins Q6 and PIN8 at the output voltages of pins 6, 7, and 8, respectively. Q15) and transistor Q16 are respectively controlled, and according to this control, to the radio calling terminal jammer transmitting unit 100 through the transistor Q14, the jammer of the mobile phone terminal through the transistor Q15. The transmitter 200 supplies power to the PS terminal jammer transmitter 300 through the transistor Q16.

The remote control infrared signal receiving means IR1 converts the received infrared signal into digital values of 0 V and +5 V, which are digital signals, and transmits the serial signal to the microprocessor U1 as a serial signal. The serial digital data is interpreted according to an internal program.

At this time, when the value of the input data is 19 (0001 1000) as a serial signal, the field effect transistor (FET) Q12 and the transistor Q13 which supply power to the driving power control unit 520 are operated. Is maintained until the next 19 (0001 1000) signal is input.

If the input data is 01 (0000 0001), the microprocessor (U1) controls the transistor (Q14) to supply power to the radio call terminal jammer transmitting unit 100, until the next 01 (0000 0001) signal is input. It will stay that way.

If the input data is 09 (0000 1000), the microprocessor (U1) controls the transistor (Q15) to supply power to the jammer transmitting unit 200, and when the next 09 (0000 1000) signal is input. It will stay that way.

When the input data is 11 (0001 0001), the microprocessor (UI) controls the transistor (Q16) to supply power to the PS terminal jammer transmitting unit 300, when the next 11 (0001 0001) signal is input. It will stay that way.

In each case, ON and OFF are controlled by the same code value. If any value is entered while the previous operation is OFF, the next is ON and the previous state is ON. In the case of (ON), the signal is turned off.
