Explanation

Answer Example

I design PCBs for high-frequency circuits by using techniques like controlled impedance trace routing, proper grounding with ground planes, and ensuring minimal trace lengths. For example, in a recent RF module design, I used a four-layer PCB, dedicated one layer to the ground plane, and routed high-speed signals with 50-ohm impedance to reduce interference. This approach improved signal integrity and minimized EMI, ensuring reliable performance.
