Coaxial Switches Economically Viable for Both Commercial and Mil/Space Applications
Coaxial switches have thus far found a niche in military and space applications because of their proven ruggedness and repeatability. Now, however, they have successfully made the transition to commercial
applications because improvements in manufacturing methods and processes have allowed them to become increasingly price-competitive.

Satellite In Orbit Group Delay Measurement Using a Microwave System Analyzer
Satellite in orbit testing is carried out for several reasons. In its basic form it is to verify the integrity of the communications payload and the antenna platform following launch and prior to the release of the satellite to the customer. Also regular checks are carried out for the purpose of acceptance testing or anomaly resolution. One parameter that has proved difficult to measure is group delay over frequency. Group delay is of prime importance in today’s communication systems.

Triplexers Deliver Pinpoint Detection for Mobile Phone Location-Based Services
Location-based value-added services are seen as the future of mobile telephony. The ability to receive GPS signals is an essential precondition. EPCOS offers a module with 3.2degree, 3.2 mm footprint for simultaneous mobile communication and reception of GPS signals.

OMAP-Vox Platform Drives 3G to the Masses
Demand for 3G wireless technology is rapidly growing in Europe and other regions of the world. To this end, it is necessary to develop methodologies that enable hardware and software solutions that scale readily across market tiers and standards while facilitating the smoothest possible transition from 2.5G to 3G technology in mass market handsets.
