2-port VNA on a 3-port Network

How to Get 3-port S-parameters From a 2-port VNA Measurement

S-parameters are fundamental quantities in signal integrity, and an ability to understand them from measurement or analysis is very important. If you have a 3-port network, like a power divider or circulator, it may appear that you must use a 3-port VNA to measure these S-parameters. It is always acceptable to measure between two ports, but you need to know what exactly it is you are measuring. In this article, we’ll look at the relationship between the true 3-port S-parameters with a 2-port measurement.

A Day in the Life of the PCB Manufacturing Process

Before implementing design for manufacturing, it is important to understand the underlying process behind producing a physical PCB. Regardless of the various technologies present in each facility, a large majority of industry-leading manufacturers follow a specific set of steps to turn your design from a drawing in a CAD application into a physical board. In this article, we'll cover the basics that designers need to know as part of our crash course series on PCB manufacturing.

Addressing Skew Sources in High Speed PCBs

If you compile a list of skew sources, you'll see that fiber weave-induced skew is only one entry on a long list of skew sources. We'll look at this list of possible skew sources below, and we'll see how they affect the operation of your PCB. From the list below, we'll see that some of these issues with skew are not simply solved by paying attention to the fiber weave construction in a PCB substrate.

Should Ground Be Placed Below Inductors in Switching Regulators?

We love answering questions from our readers and YouTube viewers, and one of the recent questions we received relates to EMI from switching elements in a switching regulator is "Should a cutout be placed below the inductor in a switching regulator circuit?". Despite the variations in inductors and their magnetic behavior, there are some general principles that can be used to judge the effects of placing ground near inductors in switching regulator circuits. We’ll look at some of these principles in this article

Top 5 Questions Regarding Stack Up

SAP (Semi-Additive PCB Process) – Top 5 Questions Regarding Stack Up

This Semi-Additive Process is an additional tool in the PCB fabricators' toolbox that enables them to provide feature sizes for trace width and spacing that are 25 microns, (1 mil) and below depending on the fabricators' imaging equipment. This provides much more flexibility to breakout out tight BGA areas and the ability to shrink overall circuit size and/ or reduce the number of circuit layers in the design. As the PCB design community embraces the benefits of this new printed circuit board fabrication technique, there are of course many questions to be answered.

Three ways to manage your BOM costs

Improving Supply Chain Success with BOM Management

It’s no secret that component shortages have become more frequent this year. In fact, countries around the world are losing billions in revenue due to supply issues. Having the right components on hand is more crucial than ever as availability, obsolescence, counterfeit products and environmental non-compliance risks continue to grow. Fortunately, many shortages can be avoided by introducing proactive supply chain practices.

Design Reuse

Rapidly Creating New Designs And Reusing Existing Ones

It's no secret that software developers often use completed code fragments from other projects for quick and predictable results. The same can be done for PCB Design, there is no need to spend time rewiring schematics or laying out components on boards you’ve done before. Join us this webinar where we’ll go over how you can use your existing designs to create reusable design blocks, speeding up the design cycle for your future projects.

Length Tuning Impedance
Blog
What is the Impedance of Length-Tuning Structures?

Do length-tuning structures create an impedance discontinuity? The answer is an unequivocal “yes”, but it might not matter in your design depending on several factors. Applying a length-tuning structure is equivalent to changing the distance between the traces while meandering. Therefore, you will have a change in the odd-mode impedance of a single trace. The question then becomes: does this deviation in trace impedance in a length tuning structure matter?

Flex and Rigid-Flex PCB Applications

There are two basic reasons for designing a flex circuit into your product: to build a compact and efficiently assembled device, or to make the circuit dynamically integrated with the mechanical function of the product. You may, of course, lean on both of these reasons for justifying the use of flex circuits. On this note, let’s look at some rigid-flex PCB applications and design examples to see the issues that spring to mind when designing flex circuits

Design Rule Checking in the PCB Design Workflow

Any time you design a PCB, and you want to turn it into a real product, you will have to make sure the design obeys the constraints within the standard PCB manufacturing process. This imposes multiple rules on any design, and ECAD software will enforce design rules as you create the board to ensure you obey these important constraints. Make sure you enforce the right design rules at the beginning of the PCB design workflow

Best Practices for High-Frequency PCB Material Selection

High frequency PCB design can seem esoteric, and I've heard many an engineer describe it as "black magic"! The subject is also a bit confusing, especially once someone asks which frequencies could be reasonably considered "high". Before you do anything inside the layout for a high-speed or RF PCB, you will need to pay attention to the materials being used in the board. If you're unsure which high frequency PCB materials you should use, then keep reading to learn more.

PCB Noise Reduction: Do You Need Isolation, Shielding, or Filters?

Of all the noise and operational challenges designers face in their PCBs, there is one overarching problem that is arguably most popular: electronic noise. It could originate as an SI/PI problem, it could possibly arise from some external source, or it could be good old-fashioned crosstalk! These tend to fall into three categories: adding shielding, doing something to create isolation, or placing filters. Let's look at all of these as they tend to be the default solution set when confronted with many noise problems.

Specifying your stackup

Communicating PCB Layer Stackup Needs to Manufacturers

In the business of PCB design, communicating needs to manufacturers and vendors is a top priority. The context of our requests is sometimes lost either by not providing the correct information, not listing enough information, or not giving any information. Although the experienced PCB designer can take steps to specify everything they want to see in their PCB stackup, eventaully the manufacturer will handle that decision in an effort to balance available materials with processing capabilities and yield.

Risk Vs. Reward

Risk Vs. Reward

During the recent IPC APEX expo, there was a lot of discussion about SAP, or semi-additive PCB processes.  As with any new technology adoption there were people that are excited to jump right in and start designing with much finer feature sizes and work through the inevitable changes to the traditional thought process. Others are in a "let’s wait and see" mode and of course there are a few skeptics there as well, so keep reading to learn more.

Parasitic Extraction with an Electromagnetic Solver in PCB Routing

Parasitic extraction: the integrated circuit design community must grapple with this task on a daily basis, especially once gate features are reduced below ~350 nm and chips run at high switching speeds. The PCB community also has to deal with this idea in order to better design power delivery networks, interconnects with precise impedance, and properly quantify crosstalk and coupling mechanisms.

Ebook: PDN Simulation and Analysis Guide

Most designers don’t realize they need to worry about power integrity until they have a power integrity problem. Other designers might build boards that can’t handle the demands of modern digital and high frequency components, and they may not realize the problems that lurk in their power delivery network (PDN). Although the basic concepts involved in designing for power integrity are well-known, myths about power integrity abound, and designers need tools to help them evaluate and qualify power integrity in a PDN.
