Drawing upon extensive experience in high-frequency circuit design, this article identifies a common pitfall: the excessive pursuit of Dk/Df parameters while neglecting temperature adaptability. Through real-world case studies, it demonstrates that for applications below 6 GHz, optimizing routing and impedance matching is far more effective than blindly selecting expensive, low-loss materials. The discussion focuses on how to strike the right balance regarding PCB substrate materials...
