IMS 2020 MicroApps: 60 GHz Phased Array Design Using XFdtd For WiGig
In this video presentation, Remcom discusses analyzing and optimizing an aperture coupled 1x4 patch antenna array with a compact, fan-shaped feeding network for operation in 60 GHz band using Remcom’s full-wave electromagnetic simulation product, XFdtd. We also demonstrate superposition and antenna array optimization. The superposition simulation provides a means for checking the performance of individual elements in an array, each with a different input power and phase. The array optimization feature allows users to estimate the excitation for each element in the array for a specified EIRP. Further, the total spatial coverage of designed phased arrays will be accurately estimated.
Designing A Practical 100GbE Real-Time Recording System For The Xilinx RFSoC
The Xilinx RFSoC provides 100 Gigabit Ethernet optical ports for streaming data from its high-speed A/D converters. 100 Gigabit Ethernet is capable of streaming data at rates as high as 12.5 Gigabytes per second. In order to capture data at these very high rates, real-time recording systems require a major upgrade in their storage technology. NVME provides a new storage protocol and interface to accommodate exponentially higher streaming data rates than previous generation interfaces. This presentation will familiarize system design engineers with PC based real-time recording systems and the latest techniques for creating an NVME PCIe type recording system.
