Connectivity Q&A: Wi-Fi Pushes The Possibilities For Our New Virtual World

The COVID-19 pandemic is a worldwide phenomenon that has affected our lives in a multitude of ways. Most notably are the periodic stay-at-home orders around the world that have shifted the way we regularly connect. According to research firm TeleGeography, in 2020, average international internet traffic increased 48%, while peak traffic rose 47%. Whether these numbers will return to pre-COVID values, or if this is the new normal, will remain to be seen. Tony Testa explores this new virtual landscape and offers some Wi-Fi specific insight into how manufacturers like Qorvo will develop solutions to help everyone adapt.

Understanding Iterative Direct DPD

Digital pre-distortion (DPD) is a common method to linearize the output signal of a power amplifier (PA), which is being operated in its non-linear operating range. This article describes an approach to generate a pre-distorted signal based on a hard-clipper. The resulting waveform pushes the output of the DUT as close to the hard-clipper as possible.
