Differential Pair Impedance Coupon Layout How to Design Test Strips
In high-speed digital and RF applications, a Differential Pair Impedance Coupon is essential for verifying that controlled impedance targets (e.g., 100Ω differential, 90Ω USB, 85Ω PCIe) are met during PCB fabrication. A single mismatch can cause signal reflection, crosstalk, and timing errors. This comprehensive guide synthesizes authoritative insights from top industry sources to provide a…
