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.
Wi-Fi Tech & Trends is Qorvo's new blog series that features questions and answers from Tony Testa, Director of Wireless Connectivity Solutions. In this article, Tony will provide insight on the latest Wi-Fi design tips, trends and innovative solutions.
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.

For an RF application, it is important to consider the advantages, disadvantages, and trade-offs of each piece of technology used. This white paper delves into the many considerations for choosing the best band pass filter for your next application and offers guidance for what to look for in each decision.
Current trends in smartphone industrial design and RF requirements mean that smartphones must fit more antennas into less space and/or increase the bandwidth of existing antennas. This article introduces four key elements to understand about antenna tuning in 4G and 5G mobile devices.
