Abstract
The mixer comprises two parallel conductors placed on each side of a substrate, two diodes mounted in series between the first ends of the two conductors, an incident-wave input connected between the second conductor-end located on the second face of the substrate and a ground line located on the first face, a mixing-wave input connected to means for applying between the ends of each diode an electric field produced by the mixing wave, and a mixed-wave output connected between at least one end of a diode and the ground line. The end of the conductor of the two-wire line is left free and electrically isolated from the ground line by means of a gap.
Claims9
A microwave mixer for producing a mixed wave from an incident wave and a mixing wave, comprising:
- a dielectric substrate having a first and a second end, and a first and a second face in parallel;
- a ground strip line conductor located on the periphery of said first face;
- a first strip conductor, having a first extremity and a second extremity, located on said first face near said first end so as to define a gap between said ground strip line conductor and said first extremity of said first strip conductor;
- a second strip conductor, having a first extremity and a second extremity, located on said second face at said first end so as to be substantially parallel with said first strip conductor, whereby said incident wave is applied between said first extremity of said second strip conductor and said ground strip line conductor;
- first and second series connected diodes, each having an anode and a cathode, said anode of said first diode being connected to said second extremity of said second strip conductor, and said cathode of said second diode being connected to said second extremity of said first strip conductor;
- means for applying an electric field produced by said mixing wave between said anode of said first diode and said cathode of said second diode;
- and
- output means, connected between said first diode anode and said second diode cathode, for providing said mixed wave.
