An RF PCB design is a bit different from a conventional board. What makes it distinct are parameters like: Impedance matching Type of traces (preferably co-planar) Elimination of via stubs (to avoid reflection) Ground planes Vias Power supply decoupling. Other aspects, such as stack-up and material selection, also play crucial roles in these boards. With all these factors in mind, the complexity of an RF design process increases due to elements like EMI interference, and high-frequency signal channeling. In this article, you will learn the 7 factors influencing your RF PCB design. 1. Impedance matching In a controlled impedance RF…
