Advantages and Disadvantages of Three Common jamming technology

1, Analog VCO technology:

• The design is simple


• low cost


• short development cycle


• It requires large power, large volume, large heat output and poor effect

2.DDS technology(Based on VCO analog technology)

• More complex than VCO analog technology


• High cost


• Longer development cycle than VCO Technology


• Better effect than VCO Technology


• Can be programmed, can select the specified band bandwidth, can allocate power


• Because based on VCO analog technology, the jamming mode is single

3.Digital source jamming technology

• The design includes hardware and software Pure digital signal source
  High cost


• Long production cycle(Digital programming and hardware design take time)


• Perfect performance (Depends on hardware design and software programming)


• Small size, light weight, low power consumption


• Different jamming modes can be loaded at the same time (Multiple jamming modes superposition)
