Abstract:
A mixer (50) separates IF components IF1, IF2 of the same frequency which are images of different frequency RF signals RF1, RF2 beating with a given LO signal, by combining a 180. degree. phase shift input (56) for the LO signal (53) and a 90. degree. phase shift input (66) for the RF signals (63) which are coupled to opposed ports (N1/N2; N3/N4) of a four port diode ring (70) and an output four port quadrature phase shifter (80). The diode ring (70) generates IF signals (71, 72) which are fed to opposed input ports (75, 76) of the output phase shifter (80) at whose other ports (81, 82) the separated image signals IF1, IF2 appear.
