As the frequency band for wireless communication shifts higher and higher, the generation of power efficient, low phase noise, broadband and configurable compact signal sources (oscillators) with low cost has become more and more challenging, due to the frequency limitations of the devices (transistors). The performance of communication systems...

Advanced Modeling in Computational Electromagnetic Compatibility Dragan Poljak Wiley Interscience • 514 pages; $125 ISBN-13: 978-0-470-03665-5 Electromagnetic compatibility (EMC) is the applied discipline within the science of electromagnetism including almost all relevant areas of theoretical (computational) and experimental electromagnetics. Theoretical methods in electromagnetics can be classified as analytical or...

The technique of directing an antenna electronically rather than mechanically has been used for quite a number of years in the military domain and more recently for space applications. The numerous advantages of this technique, including lack of mechanical parts, small sized and lightweight antennas, fast positioning, beam agility,...

Components 100 W SPDT Switch The model SWN-218-2DR-45068-MULTISPECTRAL is a SPDT reflective, solid-state switch. It is designed to handle 100 W CW with low insertion loss over narrow band­widths. Operating from 100 MHz to 2 GHz with an isolation of 40 dB and an insertion loss of only 1.5...

Conventional radiatively coupled, ultra-high frequency radio-frequency identification (UHF RFID) tags have certain limitations: they are physically large and do not operate well in or close to aqueous fluids. Recently, the use of tags configured to use inductive instead of, or as a supplement to, radiative coupling has been advanced...

Comtech Telecommunications Corp. announced that its Tempe, Arizona-based subsidiary, Comtech EF Data Corp., was awarded a $2.5 M equipment order to support a satellite-based cellular backhaul network in Asia. A leading mobile operator in the region will utilize the equipment to support a telecommunication expansion program. The order includes...

Northrop Grumman Corp. has begun work on a 62-month, $171 M system development and demonstration (SDD) contract for the first increment of a new extremely high frequency (EHF) satellite communications system for the US Air Force's B-2 stealth bomber. Under a planned three-increment upgrade program, the new EHF system...

TriQuint Semiconductor announced the release of two new satellite communications (SATCOM) high power amplifiers (HPA) that lead the industry in performance and overall size reduction. The new die-level products, TGA4916 and TGA4906, are the latest example of TriQuint’s leadership in the evolution of ground terminal sat-com RF amplifiers. The...

Rohde & Schwarz introduced the R&S ZVA-Z110 option for its R&S ZVA24 (24 GHz) and R&S ZVA40 (40 GHz) four-port vector network analyzers that allows them to make measurements between 75 and 10 GHz (W-band). The option is a cost-effective solution for evaluating the performance of millimeter-wave components designed...
