RF and microwave PCB projects pass starting functional testing but face some performance instability for high-frequency validation, volume manufacturing, or long-term working features. Common issues are: Excessive insertion loss Abnormal return loss Impedance mismatch Signal reflection EMI and crosstalk Ground discontinuity High-frequency loss caused by via transition RF performance drift after thermal cycling The main […]
