With the increase of wireless and connected devices there is a rapidly expanding need for component testing to ensure the optimal performance of these devices. The resources below are designed for people without a background in VNAs. This content will provide an introductory understanding of testing wireless or IoT devices for R&D, development, and production.
Why is it that Reflection measurements are typically only specified to -35 dB, while transmission measurements are valid to -85 or -90 dB or more? This is a common question and we get inquiries about this frequently. Brian Walker, Senior RF Engineer at Copper Mountain Technologies, explores the reasons for this in the video above, while also clearing up the contrast of Reflection and Transmission accuracy.
