Signal Isolation Structures for Electromagnetic Communications

Abstract

A signal isolation structure for electromagnetic communication is disclosed. Methods, systems, and apparatus for EM isolation structures. One of the devices includes a communication module comprising: a printed circuit board; a plurality of integrated circuit packages, each integrated circuit package including at least one transmitter, receiver, or transceiver; and one or more metal barrier structures configured to at least partially surround a corresponding integrated circuit package of the plurality of integrated circuit packages, wherein each metal barrier structure is configured to reduce signal leakage from the corresponding integrated circuit package.

Description

Technical field [0001] This manual deals with electromagnetic communication. Background technique [0002] Advances in semiconductor manufacturing and circuit design technology have enabled the development and production of integrated circuits (ICs) with increasingly higher operating frequencies. Furthermore, electronic products and systems containing high-frequency integrated circuits can provide more powerful functions than previous generation products. Additional functions usually include processing larger and larger amounts of data at higher and higher speeds. [0003] Many conventional electronic systems include multiple printed circuit boards (PCBs) on which ICs are mounted, and various signals are routed to and from ICs through them. The need to transmit information between PCBs in an electrical system with at least two PCBs has led to the development of various connectors and backplane architectures to facilitate the flow of information between PCBs. However, conventiona...

AI Technical Summary

Problems solved by technology

However, conventional connector and backplane structures often introduce various impedance discontinuities into the signal path, hinder transmission, and cause degradation of signal quality or integrity

Connecting to the PCB by conventional means—such as signal-carrying mechanical connectors—usually creates discontinuities that require expensive electronics to resolve

Conventional mechanical connectors can also wear out over time, require precise alignment and manufacturing methods, and are susceptible to mechanical shock
