  3. The Wi-Fi Evolution

    If you are looking to buy a new wireless networking gear or a mobile device, you may be overwhelmed by too many choices and abbreviations. Since Wi-Fi was first released to consumers in 1997, its standards have been continually evolving – typically resulting in faster speeds and network/spectrum efficiency – and it can be difficult to keep track of new standards. This paper is meant to help you understand the basics of Wi-Fi standards, and provides and overview of the evolution of Wi-Fi technologies.

  4. Resolving Interference In A Crowded Wi-Fi Environment Using BAW Filters (Part 2)

    There are any number of strategies that consumers can try to fix interference problems with Wi-Fi in their homes, but as an RF engineer, how can you design a Wi-Fi access point that addresses the biggest interference issues from the outset? 

  5. The Week in 5G: 9/24/2019 — Verizon 5G Lands In NYC, China Government Latest to Incentivize 5G Infrastructure Rollouts

    Plus, 4G LTE rollouts still going strong, a 5G phone for half the price of Samsung and Apple models, Austria's upcoming spectrum auction, and more, all in this edition of the Week in 5G

  6. Model-Based GaN PA Design Basics: GaN Transistor S-Parameters, Linear Stability Analysis And Resistive Stabilization

    S-parameter matching is used to maximize gain and gain flatness in simple linear RF/microwave amplifier designs. This same S-parameter data is used to develop matching networks that address amplifier stability. This paper discusses the importance of using modeling for basic S-parameter and stability analyses in the gallium nitride (GaN) power amplifier (PA) design process. It also focuses attention on a simple two-port stability analysis derived from linear S-parameter calculations. The nonlinear Qorvo GaN power transistor model from the Modelithics Qorvo GaN Library, in combination with simulation templates and Keysight Advanced Design System (ADS) software.

  7. Connectivity Q & A: Reducing Wi-Fi Interference

  9. Tolerance And Size Analysis For mmWave Filter Manufacturing

    A common question regularly asked to Knowles Precision Devices is “why not just integrate a filter in the board stack?” In short, there are manufacturing tolerances to consider, and size must also be considered. This white paper examines different 26 GHz filter manufacturing approaches with the specific design goals to better understand the importance of tolerance and size analysis.
