The well-known and extensively analyzed lumped-element bandpass filter is generally not suitable for the RF/microwave region, but there are many distributed-element, energy-based alternatives. Part 1 of this article established the context for these RF/microwave filters, which operate in the spectrum from several hundred MHz and higher, and increasingly cannot use discrete lumped-circuit elements (RLCs). Instead, […]

RF/Microwave bandpass filter implementations, Part 1: Distributed filters
The well-known and extensively analyzed lumped-element bandpass filter is generally not suitable for the RF/microwave region, but there are many distributed-element, energy-based alternatives. Just say the word “filters,” and for many engineers, the mention of this topic stirs a mix of feelings ranging from fear to relief. Why fear? Because filters as a topic in […]
The microstrip antenna, Part 2: Implementation
The microstrip antenna is a convenient, planar, easy-to-fabricate antenna with some attractive attributes and features, as well as some distinct limitations. Part 1 of this FAQ was a brief review of antennas and introduced to microstrip antenna design. This part continues that exploration along with related issues. Q: What’s the difference, if any, between a […]
Soft, conformable EMI absorber material doubles as a gap filler
Electronics are getting more compact, yet also more powerful, especially with the rise of 5G. Components packed into tight spaces produce complex signal interference issues, which can hinder device operability in automotive and other industries. But using standard EMI-mitigating absorbers as an interface between a radiating component and housing can put too much stress on […]
