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.
Remcom’s XFdtd® Electromagnetic Simulation Software contains analysis tools for rapidly characterizing the performance of arrays of antennas for beamforming and beam steering applications. This whitepaper demonstrates how unique features like superposition and array optimization simplify the process for understanding device performance by providing efficient ways to validate array coverage.
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.
In this publication, Rohde & Schwarz experts review the challenges that mode-agile (WARM) radar and EW threat emitters pose to traditional static threat library implementations in radar and EW systems, and consider the architecture of cognitive artificial intelligence and machine learning systems that can be used to deliver effective RF countermeasures.
This Skyworks white paper discusses the role of holdover and its evolution from legacy SONET/SDH networks, which depend on frequency synchronization up to modern 5G mobile telecommunication which depend on frequency, phase, and time synchronization using IEEE 1588.
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.
GaN has become the dominant RF power technology in Defense applications and higher high performance commercial applications. Strategy Analytics forecasts GaN component revenue to approach $1.5 billion for Defense applications alone by 2030. Its performance characteristics support evolving battle philosophies that rely on higher operating frequencies, wider instantaneous bandwidths, better efficiency and higher linearity. This eBook takes a look at several new applications for GaN technology and some examples of optimizing GaN amplifier performance.
With a legacy of innovative antenna design, the Advanced Technology Group of Envisticom, LLC, recently spun off as the Apothym Technologies Group, LLC (or ATG), is always in search of new antenna technologies having the potential to advance the capabilities of warfighter, satellite, and terrestrial communications. This is why the engineers with ATG sought to evaluate Fortify’s 3D printed low-loss and low-dielectric permittivity polymer resin for use in advanced antennas. With this technology Fortify engineers have been able to print extremely intricate and high resolution gradient index of refraction (GRIN) dielectric lenses that operate well at microwave/mm-wave frequencies. These lenses, impossible or extremely difficult to manufacture with traditional methods, can provide substantial antenna gain in a relatively compact shape and with minimal weight.
This case study discusses the process from design, simulation, and testing of such a GRIN dielectric lens, and provides results that show the promise of this technology in cutting-edge communications systems.
The journey from concept to full-scale semiconductor packaging is often hindered by a number of different obstacles along the way including everything from diverse teams scattered across the world to simply not understanding how the manufacturing process of die bonding, wire bonding or vacuum reflow impacts the package design and vice versa.
