Signal Integrity and Cavity Resonance Control in Duroid 6010 PCB Substrates for RF Front-End Modules

November 6, 2025by kkpcb020

Why Cavity Resonance Is the Hidden Enemy in High-Dk RF Boards In high-frequency RF front-end modules—especially those operating beyond 20 GHz—engineers often encounter unexpected resonance spikes, gain ripple, and phase drift despite ideal simulations. The culprit is frequently cavity resonance—localized standing waves caused by dielectric thickness, copper enclosure geometry, or high-Dk material behavior. ...
