Recently, Ansys released its HFSS Mesh Fusion product for simulation of complex EM systems. Signal Integrity Journal (SIJ) followed up with Dr. Matthew Commens, Principal Product Manager, HF at Ansys, Inc., to find out some more details.
Recently, Cadence released its Clarity 3D Transient Solver for EMI simulation. I caught up with Brad Griffin, product management group director for multi-physics system analysis in the Custom IC & PCB Group at Cadence to follow up for some more details.
The extension of operating frequencies in the mmWave region and beyond is the story of wireless development for the next thirty years. Understanding the resulting challenges and improving the state-of-the-art is a key driver for the EMC and wireless Industries. This article takes a look at some of the fundamentals of mmWave, including signal propagation, available spectrum, and challenges and issues facing EMC.
Richardson Electronics, Ltd. strengthens its RF offering with Masach Tech™ EMI/RFI shields. These rigid, very planar parts are designed for reflow solder and have a removable lid to allow for much easier component troubleshooting and repair.
Can common via structures transfer any data rate or are they limited with a defined bandwidth? If so, what limits its bandwidth? And what can be done when the bandwidth of the signal is greater than the bandwidth of the G-S-S-G structure? This technical feature from Dror Haviv explains.
Component manufacturers continue to develop increasingly miniaturized bulkhead filter capacitors that also offer increased current capacity, voltage, and operating temperature ranges. This post looks at the details of this miniaturization in order to help aerospace systems designers satisfy stringent size and weight constraints and further improve system performance.
Today’s vehicles support a multitude of wireless standards requiring high-performance antennas, such as satellite navigation (GNSS), tire pressure monitoring systems (TPMS), keyless entry (e.g. UWB) and cellular connectivity (4G, 5G). The challenge for tier one component suppliers and OEM vehicle designers is to ensure optimal performance of individual antenna modules and entire vehicles after the systems have been integrated.
Verifying the modulation profile of SSC has historically been challenging because it involves a frequency shift as a function of time. Mike Hertz explains that by tracking the frequency measurement parameter, an oscilloscope can display the SSC modulation profile as a function of frequency versus time. Read on to see how it’s done.
