Abstract

The invention discloses an electromagnetic wave shielding member and a transmission line assembly using the same. The electromagnetic wave shielding member comprises a quantum well structure and an electron transmission structure. The quantum well structure comprises at least two barrier layers and at least one carrier limiting layer located between the two barrier layers. The electron transmission structure is located at one side of the quantum well structure, and at least one part of the electron transmission structure has conductivity. The electromagnetic wave shielding member provided by the invention can absorb high-frequency and low-frequency electromagnetic wave noise so as to suppress electromagnetic interference.

Description

technical field [0001] The invention relates to an electromagnetic wave shield and a transmission line assembly using the same, in particular to an electromagnetic wave shield that can effectively suppress crosstalk during signal transmission and a transmission line assembly using the same. Background technique [0002] In recent years, with the development of electronic products towards thinner and smaller, high-frequency and high-speed signal transmission requirements, between various chips (such as: wireless communication chips) in electronic products, and inside cables used to transmit high-frequency signals The configuration of the transmission wires is becoming more and more dense. [0003] Accordingly, the electromagnetic wave generated by the chip can easily cause electromagnetic interference to other chips. Similarly, when high-frequency and low-frequency signals are transmitted through the transmission lines inside the cable, it is easy for two adjacent transmissi...
