Following a highly successful trial conducted from January to October 2007, the ITU Standards produced by the Telecommunication Standardization Sector (ITU-T) are now available online free of charge. The aim of the trial was to increase the visibility and easy availability of the output of ITU-T. Offering standards for...

The Institution of Engineering and Technology (IET) will be collaborating with JANET, the UK’s national network for research and education, to enable academic institutions to web stream important research seminars, conferences and lectures, via IET.tv, the institution’s web streaming service. The JANET network, which connects education and research institutions,...

The European Space Agency’s (ESA) Member States participating in the Global Monitoring for Environment and Security (GMES) Programme approved the transition to Phase-2 of Segment 1 of the GMES Space Component Programme. Oversubscription of the programme by the ESA Council at ministerial level in 2005 was confirmed, with oversubscription...

Switchmode RF Power Amplifiers Andrei Grebennikov and Nathan O. Sokal Newnes, an imprint of Elsevier • 448 pages; $89.95 ISBN: 978-0-7506-7962-6 The main objective of this book is to present all relevant information required to design high-efficiency RF and microwave power amplifiers, including well-known and novel theoretical approaches and...

SMA Attenuators Designed for volume applications and available from stock, the AHC family of SMA attenua- tors offers performance at a truly affordable price. These 2 W units operate in a frequency range from DC to 6 GHz with a 1.20 VSWR while providing excellent attenuation flatness. Built for...

Technical Handbook This 200-page, full-color technical handbook provides an overview on building test systems, including a strong emphasis on LXI. Topics include an introduction to test-system design, selection of software and hardware architecture, how to maximize system throughput, and exploring the range of networking options available for test system...

While Synchronous Optical Networks (SONET) have been widely adopted for use in long-haul applications, Ethernet is preferred in edge routers and access points due to its lower cost. Ethernet is a packet-based network architecture that is asynchronous, while SONET networks are synchronous. Hence, the two networks cannot communicate seamlessly...

With the current concentration of RF and microwave activity it is becoming increasingly important to eliminate unwanted signals so that the signal can come through loud and clear. Given the importance of providing users with filters to enable them to offer high performance equipment, Reactel Inc. has developed a...

Communication systems, test equipment and avionics are among the systems that often need to interconnect various RF modules with high performance coaxial cables. Semi-rigid cables have long been the traditional way to achieve the necessary VSWR performance at RF and microwave frequencies when delay lines or signal routing between...
