Essential PCB Design Tips for RF Circuits

Due to the distributed parameter nature of radio frequency (RF) circuits, skin effect and coupling effects can easily occur during actual circuit operation, making it difficult to control interference radiation in PCB design. For example, issues such as interference between digital and analog circuits, noise interference from power supplies, and interference caused by unreasonable grounding … Read more

Unit 8: Cavities in Printed Circuit Boards

To address the limitations of flatPCBs in integration, heat dissipation, positioning, etc., cavities are often set on their surfaces to achieve miniaturization and high performance of electronic products. Based on the structural characteristics of the cavities, they can be divided into three categories: (1) Cavities with no metal layer on the bottom or side walls … Read more
