  1. Filter Basics 11: What Are S-Parameters And What Can They Tell Us About A Filter? 11/14/2022

    In the last post in our Filter Basics series, we review the information S-parameters can tell you about a filter’s performance and show an example of how to plot a filter’s S-parameters using a free open-source tool.

  2. Understanding The Differences Between Pacemakers And ICDs 11/9/2022

    While both pacemakers and ICDs are implantable medical devices designed to improve the quality of life for people with heart arrhythmia, each device serves a different purpose.

  3. Selecting MLCCs That Meet The High-Reliability Requirements Of Medical Implantable Devices 10/26/2022

    Designing medical implantable devices for high reliability is crucial, but not straightforward. These devices are typically made up of many parts, including a variety of components such as MLCCs.

  4. Application Note: Everything You Need to Know About Wire Bonding 10/20/2022

    Today, one of the most cost-effective and flexible electrical interconnection techniques available is wire bonding. This process requires a thorough understanding of the metallurgy, thermodynamics, and surface chemistry involved.

  5. Filter Basics 10: Resonators As Microwave Devices 10/12/2022

    In part 10 of this Filter Basics Series, we discuss how resonators function as a microwave device and dive deeper into specifications for ceramic coaxial and dielectric resonators specifically.

  6. Lumped Element Filter: A Compact, Low-Frequency Filtering Option 9/23/2022

    We explore the basics of lumped element filter design, its characteristics, and how we can push filter design limits to develop a wide variety of high-performance, low-frequency filtering options.

  7. Understanding The Basics Of Ceramic Coaxial Resonator Filters 9/16/2022

    In general, a resonator is an essential component for constructing a bandpass filter since the resonator is what will allow specified frequencies, or bands of frequencies, to pass through the filter.

  8. Meeting The Unique Design Requirements For Leadless Pacemaker Electrical Components 9/14/2022

    In the last decade, innovations in technology have led to the introduction of the leadless pacemaker, which is about 1/10th the size of a traditional pacemaker, or about the size of a vitamin.

  9. Filter Basics 9: An Introduction To Poles And Zeros 9/14/2022

    In part 9 of the Filter Basics series, we go in-depth on how poles and zeros impact a transfer function to show you how you can use this information to improve your filter’s performance.

  10. Filter Basics 8: An In-Depth Look At Bandwidth 8/19/2022

    In part eight of the Filter Basics Series, we dive into bandwidth's history, how it dictates data rate, and why the filter type required depends on an application's bandwidth requirements.
