New Microwave and Wireless Technologies Study Findings Recently Were Reported by Researchers at Ramon Llull University (A Ku-band RF-MEMS frequency-reconfigurable multimodal bandpass filter)

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Microwave and Wireless Technologies. According to news reporting originating from Barcelona, Spain, by VerticalNews correspondents, research stated, "In this paper, a uniplanar RF-MEMS second-order bandpass filter with reconfigurable center frequency is presented. It is based on quarter-wavelength slotline resonators and coplanar waveguide (CPW)-to-slotline multimodal immitance inverters (MIIs), which are reconfigured using RF-MEMS switchable CPW air-bridges (SABs)."

Our news editors obtained a quote from the research from Ramon Llull University, "The filter can be adequately explained and designed using multimodal theory and circuit models. A surface micromachining process on high-resistivity silicon substrate was used to fabricate the filter."

According to the news editors, the research concluded: "Experimental results show frequency reconfiguration from 12 to 13GHz, maintaining the same relative bandwidth, and insertion losses of 4.6 and 4.7dB, respectively."
