130 Watts CW 18 To 26.5 GHz Broadband TWT Amplifier. The Model 130T18G26z5 is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where wide instantaneous bandwidth, high gain and moderate power output are required. A reliable TWT provides a conservative 130 watts minimum at the amplifier output connector
Plus, Vodafone confirms a big 5G rollout in the UK, Malaysia regulators take a hard look at 5G security, Portland, OR, wants assurances from the U.S. FCC that 5G is safe, and more, all in this edition of the Week in 5G.
This article discusses how a real-world filter’s deviation from ideal behavior needs to be quantified and that shape factor and selectivity are tools to use in this process. It touches on how both resonator Q and the filter order (number of resonators in a design) can influence a filters behavior in the transition band.
The CATV industry is looking to set new standards for the next generation of cable ecosystems, including the Full Duplex (FDX) DOCSIS 3.1, which promises to deliver 10 Gbps data rates upstream and downstream on existing hybrid fiber-coaxial (HFC) systems. Achieving FDX will require highly linear devices enabled for digital predistortion (DPD) — including 75-ohm CATV switches. This article explores how DPD works in CATV optical nodes, as well as some considerations for selecting the right switch for each application.
Plus, Nokia and KT expand their 5G rollout collaboration, Sprint touts its 5G strategy over competitors' approaches, AT&T rushes to trial its 24 GHz gear before the FCC's 24 GHz auction, and more, all in this edition of The Week in 5G.
In the near future, 5G New Radio (NR) will need to have ultra-fast download speeds, reliable low latency connections, and connectivity to billions of new IoT devices coming online. Spectrum is a key enabler to meeting these goals. However, today’s spectrum is already crowded and the introduction of new operating bands increases the potential for side-band interference, and sometimes overlap with previous spectrum allocations. Device designers must ensure that new 5G NR designs meet target performance and coexist with 4G, Wi-Fi, and other wireless communication systems sharing overlapping spectrum. This white paper discusses the issue of 5G spectrum coexistence issues and presents techniques for minimizing interference and operating in shared spectrum.
