More than ten years ago LDMOS transistors were introduced as a replacement of bipolar transistors for RF power applications [1,2]. Nowadays LDMOS technology is the leading RF power technology for base station applications, in particular for GSM-EDGE applications at 1 and 2 GHz, WCDMA applications at 2.2 GHz and...
Two trends are well underway in portable and handheld consumer electronic devices: shrinking form factors and the integration of multiple wireless technologies, such as Bluetooth™, cellular, GPS and Wi-Fi. These trends create challenges for device vendors and integrators by increasing the likelihood of RF noise and other system interactions...
The Need to Amplify Signals An amplifier is one of the most common electrical elements in any system. The requirements for amplification are as varied as the systems where they are used. Amplifiers are available in a large number of form factors ranging from miniscule ICs to the largest...
In the ten years preceding the last Tri-Service Symposium (1960) on the “Biological Effects of Micro-waves,” a considerable community of researchers participated in the study of interaction of microwaves with biological systems, particularly animals and man. Military standards were confirmed at 10 mw/cm2 maximum permissible exposure levels based on...
Under the banner of 75 Years of Driving Innovation , Rohde & Schwarz invited more than 200 guests from around the world to celebrate its landmark 75 th anniversary at its state-of-the-art Technology Center in Munich, Germany, which opened in 2005. The Prime Minister of the State of Bavaria,...
The recent Roke Manor sponsored November ARMMS Conference in Corby UK, attempted and succeeded in breaking new ground at a juncture that the ARMMS chairman, Roger Hopper, described as, “interesting times”. To stimulate debate and attract a wider and more inclusive audience the program coordinator, Dominic FitzPatrick of Cardiff...
Robert Bosch GmbH will be employing a chip from Infineon Technologies in its next generation of automotive radar systems. Bosch, one of the world’s largest suppliers of components for the automotive industry, has chosen a chip from Infineon’s Radar System IC (RASIC™) product family for use in its new...
SUSS MicroTec Test Systems has won a head-to-head evaluation with its PA300PS with ProbeShield® Technology, the 300 mm wafer-level probe system for device characterization and reliability test. As a result, the major US integrated device manufacturer (IDM) has named SUSS as its exclusive supplier of on-wafer characterization systems for...
This issue concludes our celebration of 50 years serving the microwave industry. We hope you have enjoyed this year- long look at our shared history—the reprints of past articles and special retrospective reports, as well as the projections of the future by all our guest contributors. Without a doubt,...
Recent developments have reinvigorated clinical investigations of hyperthermia (HT) as a viable adjuvant treatment in the fight against cancer. Researchers are placing a greater emphasis on multi-modal approaches that include mild temperatures (40° to 43°C) and standard therapies like radiation and chemotherapy, than on achieving higher temperature treatments (43°...
