  1. Factors Affecting Temperature Rise In MLC Capacitors

    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.

  2. Flexibility Of Multilayer Ceramic Capacitors

    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™.

  8. 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.
