The advantages of multilayer ceramic capacitors over plastic film types include their smaller physical size, lower inductance, and ability to operate at higher temperatures. These advantages make MLC capacitors well suited to high power applications, such as power converter systems in electric and hybrid electric vehicles. When selecting a capacitor to operate at high temperatures, it is useful to understand how its operating conditions can affect its working temperature. This application note explores the factors that affect the working temperature of an MLC capacitor.
Mechanical cracking resistance can be increased by two methods; by reducing the mechanical stress being exerted on the capacitors by PCB design/assembly processes, and by increasing the mechanical strength of the component. This article takes a look at both approaches and will examine Knowles Capacitors’ approach to increasing the mechanical strength through FlexiCap™.

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.
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?

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.
