PCB Considerations For Defected Structures

As strange as it may sound, the use of circuit defects is a growing trend in high-frequency circuit design, especially for passive circuits such as filters. More precisely, the trend is in the increased use of defected ground structures (DGSs) and defected microstrip structures (DMSs) to alter the responses of microstrip circuit designs. Just what are these DGS and DMS forms, and does incorporating them into a high-frequency circuit change the way the PCB material should be specified?

Learning To Launch Onto Different Circuit Thicknesses

No Comments
The transition, from a waveguide or coaxial connector to the PCB, is critical to the performance of the circuit, and the PCB’s thickness can impact how an end launch transition is made. Waveguide and coaxial connectors come in many shapes and sizes, as do PCB thicknesses, and matching the connector to the substrate thickness can play a large role in the overall performance and reliability of that design.

Off to the Races: Creating Winning Finishes

3 Comments
As promised, we are off to the races, untangling the convoluted subject of PCB surface finishes.  This is a complicated subject, so bear with me as I try to break it down into bite-sized, manageable portions! This week I will discuss each available surface finish and the pros and cons of each one.
