When designing PCBs for 5G network systems, the components will need Mm-wave frequencies of 28GHz, 30GHz, and even 77GHz based on the application. This means that components are transmitting and receiving frequencies that can range from 600 MHz up to 5.925 GHz and bandwidth channels of 20MHz, or 200kHz for IoT systems. Most systems now are handling 4G and 3G PCBs. Mixed Signal Acceptance Circuit Board Designs Also, challenges to the PCB design will need to be addressed, such as maintaining the signal integrity at those higher speeds, dealing with thermal management, and what to do to prevent electromagnetic interference (EMI) between digital and analog boards.įigure 1: Depiction of 5G technologies for better connectivity. The 5G PCB will have to address all the specifications when carrying and receiving signal transmissions, providing electrical connections, and offering controls for specific functions. So, what does this mean to the high-speed PCB industry? Material considerations will be the top aspect that will have to be evaluated for designing and building the PCB stack-up. The dizzying speeds of 5G will open new market opportunities to all industries that will use, design, and manufacture the components and applications that will use these systems. More mobile wireless communication systems are upgrading and converting over their processes to adopt 5G technologies for better connectivity to the Internet of Things (IoT) (Figure 1). Should we say that fifth generation (5G) technology has arrived? Yes. High-Speed PCBs and 5G Technology Considerations and Challenges
