This post breaks down the basic properties impacting capacitor and inductor performance including resistance, inductance, and impedance.
In part 2, we cover how RF designers can use the different frequency dependencies of capacitors and inductors to manipulate impedance and create various filter responses.
In part 3 we aim to help simplify filter selection by providing an overview and reference point for five of the most commonly discussed filter technology specifications.
In part 4 of this series we provide overviews of the main filter types and key filter technologies available today.
Part 5 dives into more detail on lumped element and distributed element filter construction techniques and when each option is most appropriate to use based on your application.
Part 6 expands on part 5 by covering more details on waveguides and transmission lines, including the different types of electromagnetic modes supported by each.
Part 7 provides a deep dive on the different ways to think about Q factor for the components going into your filter or your filter as a whole.
In part 8, we dive deeper into bandwidth by looking at the history of bandwidth, how bandwidth dictates data rate, and why the type of filter required will vary depending on an application’s bandwidth requirements.
In part 9, we go in-depth on the background information of how poles and zeros impact a transfer function to show you how you can use this information to improve your filter’s performance.
In part 10 we discuss how resonators function as a microwave device and dive deeper into specifications for ceramic coaxial and dielectric resonators specifically.
In part 11, 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.
