RF Microtech Develops Complex UWB Filter In Record Time

on 19 Apr 2017 in News | 0 comments

Another success story for RF Microtech. A great achievement for the company, whose outcomes in projecting Complex UWB Filter have been published by AWRCORP, but also exalted on the Microwave Journal (see the links below) The Design Challenge Expo Milano 2015 was a universal exposition that hosted over five thousand events in six months. The organizers had contracted with several mobile service providers to deploy stations throughout the expo area to provide complete mobile service coverage for the event. In addition, Italian government security services relied on mobile base stations strategically placed throughout the expo to ensure communications for the event, including the public safety network. However, the lobe of one of the mobile service antennas directly interfered with the communication signals of a critical security control base station and the issue had to be resolved immediately as the expo was opening in less than a month. RF Microtech was asked to provide a validated full-wave electromagnetic (EM) simulation of a 2-port ultra-wideband (UWB) filter that could reject all five mobile service bands with greater than 35 dB of rejection. Furthermore, the filter had to ensure 80 MHz to 6 GHz wide-band transmission with insertion losses less than 2 dB RF Microtech’s client, H3G, also required that the device fit within a 1x1x0.2 meter enclosure, while still providing acceptable levels of coexistence to 6 GHz without signal degradation. The validated EM simulation had to be delivered within two weeks and the complete deployable device by the time the expo opened. The Solution “We chose Microwave Office because it could easily and quickly optimize the cascade of a series of full-wave component blocks of a very large and complex UWB filter structure. Using Microwave Office, we were able to reduce optimization and development time by 90 percent, a critical factor in delivering this project in a very short timeframe.”stated Roberto Sorrentino Honorary President of RF Microtech The RF Microtech design team immediately went to work developing a circuit model of five independent notched-band filters (NBFs) cascaded along a transmission line. The team chose NI AWR Design Environment, specifically Microwave Office circuit design software, for this time-critical project. Each independent filter was designed as a 4th or 5th order NBF, composed...

Microwave and RF Engineering – Chinese Edition

on 6 Sep 2015 in News | 0 comments

The book by R. Sorrentino (RF Microtech’s co-founder) and G. Bianchi Microwave and RF Engineering (edited by Wiley) has now been translated in Chinese. This outstanding book is an essential text for both students and professionals, combining detailed theory with clear practical guidance. It explores a large spectrum of topics within microwave and radio frequency (RF) engineering, encompassing electromagnetic theory, microwave circuits and components. It provides thorough descriptions of the most common microwave test instruments and advises on semiconductor device modelling. Microwave and RF Engineering presents up-to-date research and applications at different levels of difficulty, creating a useful tool for a first approach to the subject as well as for subsequent in-depth study. It is therefore indispensable reading for advanced professionals and designers who operate at high frequencies as well as senior students who are first approaching the...

Microwave Career Award

on 17 Apr 2015 in News | 0 comments

RF Microtech is proud to announce that its Founder and Honorary President, Prof. Roberto Sorrentino, has been selected to receive the 2015 Microwave Career Award of the IEEE Microwave Theory and Techniques Society (MTT-S). This award recognizes an individual for a career of meritorious achievement and outstanding technical contribution in the field of microwave theory and techniques. He’s the first Italian to receive this award since its institution in 1973. The citation reads: “For a Career of Leadership, Meritorious Achievement, Creativity and Outstanding Contributions in the Field of Microwave Theory and Techniques.” The Past Awardees list sees, among the others, names of scientists who made the history of Microwaves: Mumford, Wheeler, Whinnery, Weber, Cohn, Tomiyasu, Oliner, Marcuvitz, Matthaei, Young, Cullen, Pucel, Saad, Kurokawa, Rosen, Itoh…and many more. The award will be conferred at the annual Society Awards Banquet to be held in Phoenix, Arizona, during the International Microwave Symposium, 17-22 May...
