What is Dielectric Constant or Dk?
Best Practices for High-Frequency PCB Materials Selection High frequency PCB design can seem esoteric, and I've heard many an engineer describe it as "black magic"! The subject is also a bit confusing, especially once someone asks which frequencies could be reasonably considered "high". The reality is that some of the challenges present in high speed design also appear in high frequency design, but we think about them in different ways. Before you do anything inside the layout for a high-speed or RF PCB Read Article
Use the Best RF Design Software for High Frequency PCBs Designing radio frequency systems to support high frequencies and digital interfaces is challenging and requires the best RF design software tools. RF engineering in a high GHz band takes the best RF design software to ensure accurate PCB trace routing, layer stack design, and circuit design. Use Altium Designer for your RF design process and to take your next GHz band system to manufacturing. ALTIUM DESIGNER A unified PCB Circuit design software Read Article
Substrate Integrated Waveguide Routing for mmWave PCBs A substrate integrated waveguide acts similar to optical fibers The applications of mmWave signals used to be confined to defense, but now mmWave systems are becoming more common. You can thank car radar, UAV radar, upcoming rollouts of 5G, and current research on 6G for bringing mmWave technology into the mainstream. Routing with mmWave signals has forced designers to rethink their routing practices and interconnect designs. This has motivated Read Article
