So if I measure the null-to-null spacing in the S11 plot from a non-50 ohm transmission line and then calculate the delay using your formula given earlier: delta f in GHz) = 1/(2*Td) is Td also the group delay? Will a non-consistent group delay issue show up as variation in the measured S11 null-to-null spacing?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
