Multicast ABR, DVB-S2X, GSE, Time Slicing: Enabling Cost Effective Delivery Of Live Video Streams Via Satellite
 
By Christophe Trolet, TeamCast, and Jérémy Desmauts, Broadpeak

Many satellites are used to provide infrastructure for live broadcasting to large geographical areas. However, the bandwidth resources are expensive and unfit for delivering unicast content, which requires resources that grow linearly with the number of users, making the use of satellites seem an impractical solution. This white paper explains how satellites may be used to deliver live content to a wide range of connected devices in a way that is transparent to the existing components.

Spotlight On Satellites/Space-Qualified Components
High Stability And Low Power Demand In A Compact Oscillator

Greenray Industries' T75 Series TCXOs (temperature compensated crystal oscillator) utilize AT Strip crystals that deliver distinct advantages over normal circular blank crystals such as lower g-sensitivity, reduced crystal perturbations, and improved aging performance.

Group Delay and Phase Measurement on Frequency Converters

Frequency converters such as those found in satellite transponders need to be characterized not only in terms of amplitude transmission, but also in terms of phase transmission or group delay, especially with the transition to digital modulation schemes. 

High-Performance Components For Space Applications

KRYTAR, Inc. specializes in designing and manufacturing a wide range of ultra-broadband, high-performance microwave components and test equipment designed to cover RF, microwave, and mm-Wave frequencies within commercial and military space applications. 

Top 4 Sources Of Microvibration On Spacecrafts

It is vital to understand how to design a spacecraft with precise functionality for the journey to earth’s orbit and beyond. Eliminating as many vibrations as possible is crucial so they do not interfere with functionality during pre-launch transportation and powered flight. One type of vibration is microvibrations. 

Communications/Data Link Products

Amplifiers specific to communications systems include a wide range of Solid State Power Amplifiers (SSPAs) and Low Noise Amplifiers (LNAs) originally from Paradise Datacom, a business unit of Teledyne Microwave Solutions, and a range of organically developed products within TMS.

RF Breakdown Analysis In Space Applications

Devices in the output section of a satellite payload are subject to high RF power, which could lead to RF breakdown, rendering the device useless and degrading the satellite’s reliability. For this reason, all space high-power devices have to be analyzed in regards to their breakdown behavior.

Connections For Space

The new Space brochure shows HUBER+SUHNER products for applications in satellites, as well as for simulated tests in and around the pressure chamber.

Qorvo Spatium SSPA Technology

Qorvo’s offers patented Spatium RF power combining technology to provide a highly reliable, efficient alternative to traveling wave tube amplifiers (TWTAs) for commercial and defense communications, radar, electronic warfare (EW), and other defense systems.

Webinar: 2016 FEKO Student Competition Winning Entry
 

Daniel Ung's entry was selected as the winner of the 2016 FEKO Student Competition. FEKO was utilized to produce a beam model of the Murchison Widefield Array radio telescope. The method involved the use of embedded element pattern simulation with spherical harmonics representation. In this webinar, Daniel will present his report detailing how he made use of FEKO, Altair's electromagnetic simulation tool.
