A common question regularly asked to Knowles Precision Devices is “why not just integrate a filter in the board stack?” In short, there are manufacturing tolerances to consider, and size must also be considered. This white paper examines different 26 GHz filter manufacturing approaches with the specific design goals to better understand the importance of tolerance and size analysis.
5G promises a spectacular world of wireless communications systems. This white paper addresses the complexity of designing various points in these kinds of systems, and discusses how ANSYS products are a possible solution to design and simulate antenna systems, antenna-to-antenna coupling, environmental effects on signal propagation as well as V2V and V2X communication for traditional and autonomous vehicles.

Analog Devices recently launched a pair of highly integrated microwave upconverter and downconverter chips operating over a wide frequency range with 50 Ω match from 24 GHz up to 44 GHz. Performance attributes of the ADMV1013 and ADMV1014 ease the design and implementation of small 5G millimeter wave (mmW) platforms that cover the popular 28 GHz and 39 GHz bands in backhaul and fronthaul, as well as many other ultrawide bandwidth transmitter and receiver applications.
With a tremendous increase in the number of connected devices and mobile data demand predicted over the next decade, the wireless communications industry is exploring new technologies to accommodate 5G wireless data systems, including MIMO (multiple-input, multiple-output) technology and millimeter wave frequency bands. One of the more complex environments for these technologies are urban small cells, where the prevalence of multipath and non-line-of-sight conditions leads to many challenges, particularly at higher frequencies.
There are any number of strategies that consumers can try to fix interference problems with Wi-Fi in their homes, but as an RF engineer, how can you design a Wi-Fi access point that addresses the biggest interference issues from the outset? This is the second article in a 2-part series looking at design challenges for Wi-Fi front-end designs.
AR’s new poster on Multi-Tone Immunity testing provides a reference to show just how AR’s MultiStar Multi-Tone tester can maximize your efforts by testing multiple frequencies simultaneously, thus increasing test speed and eliminating costly chamber bottlenecks.
