Minimizing reflections and signal losses in test systems associated with the design, manufacture, and production of RF products can be a complex challenge. In addition to issues such as cable and interconnect quality, engineers must consider conductor length, physical layout, and other aspects of system design that have little effect on DC circuits, yet are fundamental to the satisfactory operation of high-frequency RF systems. Understanding and dealing with the mechanisms of impedance matching and signal loss are crucial in designing test systems for wireless products.
