Analog Devices Inc. (ADI) introduced a D/A converter that brings the future of television to today's home viewers, enabling them to enjoy ultra–high-definition (UHD) and 4K television across more channels at unprecedented streaming and download speeds.

Satellite operator SES S.A. will pay $730 million to acquire the remaining shares and warrants of O3b Networks, a 12 satellite constellation in medium earth orbit that provides communications services to remote regions.

MaxLinear's purchase of Broadcom's and Microsemi's wireless infrastructure businesses gives MaxLinear more credibility in wireless infrastructure.

Teledyne Defence, a business unit of Teledyne Microwave Solutions, announced that it has been chosen by OneWeb Satellite for the supply contract to produce hundreds of space-qualified ‘flexible channelisers’ for its global satellite constellation deployment.

The newest 802.11 standard, 802.11ax, is taking things one step further by promising to deliver that connectivity faster, over the 2.4 GHz or 5 GHz band by utilizing OFDM, up to 1024 QAM, and multi-user MIMO. Read about its measurement challenges and solutions.

Azimuth Systems Inc., a leading provider of automated, real-world mobile performance test solutions, announced that Quantenna Communications Inc., a leading developer of 802.11ac and 802.11n semiconductor solutions for the next generation of ultra-reliable Wi-Fi networks, has selected the Azimuth’s scalable automated RF platform, Spider™, for its wireless development and product testing, and for its system verification within its ecosystem of carriers, home networking, and consumer electronics vendors.

Silicon Labs introduced a family of jitter-attenuating clocks that simplifies 100G/400G coherent optical line card and module design by providing a high-frequency, flexible clocking solution that significantly reduces system-level cost and complexity. Silicon Labs’ new Si534xH coherent optical clocks replace discrete timing solutions that rely on expensive, large-footprint voltage-controlled SAW oscillators (VCSOs) to provide low-jitter reference timing for data converters. Unlike VCSOs that support single, fixed frequencies, the new Si534xH clocks operate over a wide frequency range, supporting frequencies up to 2.7 GHz without the need to change bill-of-material (BOM) components.

Broadcom Ltd. announced a new dual-channel 5GHz Wi-Fi access point platform designed to enable enterprise and public venue operators to optimize performance for all connected devices. The Broadcom® 5G-HD platform is built on the new BCM49408 quad-core CPU, enabling client devices that are 5GHz 11ac-capable to maintain the fastest possible speeds by eliminating performance degradation that occurs when slower client devices share traditional single channel 5GHz Wi-Fi access points.

TowerJazz, the global specialty foundry leader, announced its SiGe Terabit Platform targeting high-speed wireline communications for the terabit age. Wireline data traffic is increasing dramatically, with traffic at Google famously increasing by 50 times over the last six to seven years, or at 75 percent per year. Estimates vary, but experts agree on double digit CAGRs and a 2020 market for high speed optical components in excess of $9 billion. TowerJazz addresses this market through a family of customized foundry silicon-germanium (SiGe) BiCMOS technologies and is announcing availability of its highest performance process to date: S4.
