Virtual Panel Session: Will Open RAN Work?

Dec 8th 11 am ET /8 am PT

Open RAN promises to lower network costs and barriers to entry to create competition through the standardization of hardware and software but will is work? Experts from Keysight, Qualcomm, ADI, Xilinx and VIAVI debate the pros and cons - moderated by Joe Madden of Mobile Experts.

Understanding Suspended Substrate Stripline Filters

Suspended substrate filter technology uses air cavity construction achieve high Q and avoid the adverse effects of dielectric materials used in traditional stripline construction. The resulting performance gives designers the advantages of wide passbands with low insertion loss and stopband rejection on the order of 100 dB with fast roll-off. This paper reviews the fundamentals of suspended substrate filters, key performance features and the unique manufacturing challenges associated with these useful building blocks for wideband systems.

RF to Millimeter-Wave Front-End Component Design Trends for 5G Communications

RF front-end architectures grow more complex with each generation of communication systems. To accommodate these architectures, more densification and miniaturization is taking place with electronic systems implemented through innovations in system-in-package (SiP) design. Cadence offers the broadest, most integrated design solution to bring the Intelligent System Design™ strategy to the communication products of the future.

Automatic Fixture Removal with Copper Mountain Technologies VNA

Automatic Fixture Removal (AFR) is a simple and an accurate way to de-embed a measurement fixture. These fixtures are typically used when measuring Surface Mount Device (SMD) type components to provide an interface from the Vector Network Analyzer (VNA) test port cables to the Device Under Test (DUT). The main challenge when characterizing such components is to completely isolate the actual DUT characteristics from the fixture; which becomes even more challenging at higher frequencies.

Phased Array Antenna Patterns—Part 3: Sidelobes and Tapering

In Part 1, we introduced the phased array concept, beam steering, and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of antenna sidelobes and the effect of tapering across an array. Tapering is simply the manipulation of the amplitude contribution of an individual element to the overall antenna response.

Comparison of Time Domain Scans and Stepped Frequency Scans in EMI Test Receivers

Taking the R&S ESR EMI test receiver as an example, this paper looks at a CISPR 16-1-1- compliant test instrument with time domain scanning capabilities. The paper compares the measurement speed and level measurement accuracy of a conventional stepped frequency scan versus an advanced FFT-based time domain scan. It also contains guidance on making optimum use of time domain scans.

Benefits of Foam Polymers in HUBER+SUHNER Low Loss SPUMA and Phase Stable CT Cables

Phase-critical analog and digital transceiver systems are increasingly relied upon in global Aerospace & Defense programs, due, in part, to the rapid advancement and growth of high-resolution phased array antenna technology. These advancements are enabling significant innovation in satellite-based communications (SATCOM), surface, airborne, and space-based radars, secure point-topoint communications, autonomous vehicles, electronic warfare (EW), and space research.
