These low-loss components feature 20-dB isolation in standard 2-GHz configurations, with wider bandwidths and higher isolation also available. The isolators are typically used to buffer the outputs of amplifiers and oscillators while the circulators serve as signal duplexers on transceivers with a single antenna. An example of an isolator is Model HMI28, built with WR-28 waveguide.</p></div> <div class="og_rss_groups"></div><p><a href="http://mwrf.com/news/isolatorscirculators-extend-120-ghz" target="_blank">read more</a></p> http://mwrf.com/news/isolatorscirculators-extend-120-ghz#comments News Fri, 04 Apr 2014 15:18:00 +0000 24231 at http://mwrf.com Coaxial Switches Trim PIM to 18 GHz http://mwrf.com/news/coaxial-switches-trim-pim-18-ghz <div class="node-body article-body"><p>A line of coaxial switches from Radiall features low levels of passive intermodulation (PIM) for use in different systems and test applications.
