2. SystemIntroduction
2.1 SystemDiagram
The Cell phone jammer includes 12 independence channels (12 Bands), which combine:
VCO- Voltage-Controlled Oscillator
PLL- Phase Locked Loop
VGA- variable-gain amplifier
PA- Power Amplifier
VCO produce original CW signal for each channel, its working frequency be set range 390~395MHz by
controlling PLL output frequency via MCU (Monitor Control Unit), the OCXO (Oven Controlled Crystal
Oscillator) provide reference clock signal to increase signal stability.
VGA use to set channel gain and control channel output power.
PA output power 30~35dBm
The output signal from PA is then fed to antenna with 33dBm/channel output power which retransmits the
signal to the aim areas.
