Wideband RF Launches:  Much more than Footprints on PCBs

As the demand for higher frequencies and wider bandwidths continue their relentless march upward, RF connectors need to keep up with, or even exceed, demands. Mating the RF connector to a PCB or substrate requires careful consideration of several factors to get the full performance out of the connector. This white paper will provide an understanding of what makes successful launches work, what knobs to turn, and design guidelines to make connector launches perform well as the industry moves toward 100 GHz bandwidths.

What Really Matters? ESD Specifications for Smartphone Antenna Tuners

Antenna tuners in smartphones, like other electronic components, must be able to withstand electrostatic discharge (ESD) at every stage from device manufacturing and smartphone assembly to consumer use. Rather than rely on legacy assumptions, tuner selection should reflect the manufacturing systems and standards of today. Learn more to protect your devices.

Persistent Spectrum Monitoring

This article will introduce the three trends driving the need for persistent spectrum monitoring before comparing the benefits of a proactive approach to traditional RF drive tests which are often reactive and capture only a brief snapshot of the wireless environment. It will conclude by highlighting some of the key features and performance requirements RF Engineers should consider when comparing RF receivers.

Advances in EM Analysis and Design Flows for RF System Development

RF/mixed signal PCB systems and heterogeneous SiP technologies are increasingly susceptible to delayed product development turnaround times due to higher frequencies and component densities. This paper overviews the Cadence design platforms that provide seamlessly integrated EM and multiphysics/thermal simulation with the capacity to solve large-scale design and integration problems across IC, package, and board.

Filtering Solutions for 5G C-Band Interference with Radar Altimeter Receivers

Recent debate about potential interference between 5G network equipment operating in C-band frequencies and radar altimeter (RA) receivers onboard commercial aircraft has highlighted the need for high-Q filtering solutions in crowded spectral environments. This paper presents two Mini-Circuits filters fabricated using ceramic resonator and cavity technologies designed specifically to eliminate interference by 5G C-Band emissions when incorporated either within or in line with the RA assembly.
