19CD328 Image

The 19CD328 from Smiths Interconnect is a low power waveguide circulator that operates from 18 to 20 GHz. It can handle a CW input power of 2 W, has an insertion loss of less than 0.15 dB and provides more than 23 dB of isolation. The circulator has been specifically designed for waveguide demultiplexers (channel droppers) and is arranged mechanically to be cascaded to suit the number of channels required. It is used in conjunction with a compact termination which allows maximum flexibility to create an isolator with the loaded port selected to suit the designer’s mechanical constraints. The circulator is available in a module with WR51 waveguide interface and is suitable for satellite communication payloads in GEO/MEO and LEO orbits.
