In August 2022, Nordic Semiconductor announced its first Wi-Fi product. The nRF7002 is a dual-band (2.4 and 5 GHz) Wi-Fi 6 compatible companion IC. It does not have a general-purpose microcontroller built-in. Instead, Nordic intends for you to combine it with another microcontroller, like one of their nRF52 or nRF53-series system on chip (SoC). https://youtu.be/U3aBK9OM1OQ Nordic and the element14 Community sent me an nRF7002 Development Kit (DK), Evaluation Kit (EK), and some nRF7002 QFNs. I…

Vector network analyzers (VNAs) measure how a “network” of components changes the amplitude and phase of signals. By measuring across a wide frequency range, VNAs can create S-Parameters that fully describe the behavior of a circuit. This video uses a PicoVNA 106 to show the basics of what a VNA measures, how they work, and a brief overview of how to use one. I made a mistake on the explainer graphic for S-parameters. The annoying…
