摘要：A combined duplexer/mixer especially for use in an FMCW millimetric radarsystem has a waveguide section containing a fin line or suspended strip structure forresponding to the linearly polarized radar return signal passing through the section inone direction while permitting passage of the orthogonally polarized, outgoing signalpassing in the other direction. The fin line is coupled via double balanced mixer diodes toan IF output line to produce an IF signal by mixing the return signal with a portion of theoutgoing signal tapped off by a field distorting probe, ridge section or like couplingmeans.
