Description
Technical field
The present invention relates to information electronic industry millimetre-wave attenuator technical field, particularly relate to a kind of millimeter waveguide communication system of being carried out point-to-point transmission transfer of data by millimeter waveguide, this millimeter waveguide communication system can be used as the bus of high speed data transfer between processor and memory.

For CMOS (Complementary Metal Oxide Semiconductor) (CMOS) transistor fabrication based on silicon, replacement scheme more effective and not more economical at present.Further, the Recent Progresses In The Development of composite material is also slower.And the transmission of data becomes the principal element of limiting computer performance.For the high speed data transfer on sheet and on plate, when signal rate is close to 10 × 10
9b/s, the inherent characteristics such as the skin effect of transmission line and self inductance effect start significantly.More difficult differentiation between the bit of transmission, the probability be correctly decoded reduces, and synchronous signal integrality worsens serious.Along with transmission on the transmission line, square wave can broaden and die down.Sometimes the effect of dispersion of substrate can be stronger than copper transmission line self dispersion, more limits systematic function.These factors make copper cash greatly reduce for the distance transmitted.Usually, these problems can be made up by predistortion, active amplitude equalizer and clock recovery etc.But, can corresponding increase power consumption for the circuit module of clock recovery, Active Equalizer and preprocessor.In addition, in order to obtain higher throughput, the simple width by increasing copper bus is also infeasible.Because the increase of highway width, the increase of number of channels attenuating and power consumption, needs the increase of the input/output end port of ground connection simultaneously.
The selection substituting of copper bus potential is light bus.At multimode fiber or do not have on the polymer waveguide of pernicious decay or distortion to the signal of certain wave band, the transmission range of signal can reach several centimetres even several meters far away.But single-bit consumption more energy during light bus data transfer.Although new lasing light emitter can directly modulation to 30 × 10
9about b/s, and have enough reliabilities.But that does like this is arm and a leg, and uncertainty may be born.The most important thing is, light bus still do not have can large-scale production, the ripe integrated technique of reliable and economic.
