Millimeter wave waveguide communication system

Abstract

The invention provides a millimeter wave waveguide communication system. The millimeter wave waveguide communication system comprises a clock module and at least two groups of millimeter wave receiving / sending channels, wherein the clock module is used for respectively providing clock signals for the sending ends and receiving ends of the at least two groups of millimeter wave receiving / sending channels; each group of the millimeter wave receiving / sending channels comprises an emitter module, a receiving end module and a transmission waveguide, wherein the transmission waveguide is positioned between the emitter module and the receiver module and is used for providing a transmission channel for the millimeter wave; the areas on the top, side and / or bottom of the transmission waveguide, except part of areas on which active devices and accessories are arranged on, are plated with metal conductive walls to form electromagnetic shielding of the transmission waveguide in the adjacent millimeter wave receiving / sending channels. The metal conductive wall of the layer can minimize the crosstalk between the channels during high-speed communication, and therefore, data bandwidth and data throughput of the millimeter wave communication system are improved.

Description

technical field [0001] The present invention relates to the technical field of millimeter wave communication in the information electronics industry, and in particular to a millimeter wave waveguide communication system for data transmission between two points through a millimeter wave waveguide. The millimeter wave waveguide communication system can be used as a high-speed data link between a processor and a memory. transfer bus. Background technique [0002] Traditional computer hardware is based in part on three ubiquitous and well-established technologies: silicon, used to form transistors for logic operations, memory, and signal amplifiers; composite materials, used for isolation for discrete component integration; and copper, used for data transmission.

Problems solved by technology

[0006] However, the applicant realized that the above-mentioned millimeter-wave communication system has the following technical defects: (1) There is a phenomenon of millimeter-wave leakage on the outer surface of the plastic waveguide, which leads to an electric field leaking around the plastic waveguide, extending about one wavelength. In order to reduce For the coupling of the leakage electric field, there must be a sufficient distance between the waveguides, which indirectly increases the size of the waveguide and reduces the number of waveguides; (2) At both ends of the waveguide, there is a phenomenon of millimeter wave reflection, which leads to the transmission The quality of the signal is reduced; (3) The refractive index of the plastic waveguide is low, which makes the characteristic size of the signal channel larger, and the size of the waveguide becomes larger, resulting in a reduction in the number of waveguides in a limited range; (4) The waveguide used to generate the millimeter wave carrier Mixers and voltage-controlled oscillators are all pure circuit structures, which increase the power consumption and noise of the entire millimeter-wave communication system, especially the phase noise of the demodulation circuit, which leads to an increase in the bit error rate of transmission and indirectly affects the signal to be transmitted modulation rate

The above four technical defects all affect the data bandwidth to a certain extent, reduce the total data throughput, and are not suitable for systems like high-performance computers
