Abstract
A mixer comprising two microstrip plates, each having an earth plane, a dielectric layer and an etched layer. One of the etched layers carries the mixer ring and input guides. The outer etched layer carries the output guide and the tuning members. The plate are joined by their earth planes and the mixer diodes are placed in the holes connecting the two etched faces.
Claims7
An ultra-high frequency hybrid mixer which comprises:
- a first dielectric layer having first and second faces;
- a second dielectric layer having third and fourth faces;
- at least one conductive layer having a fifth face fixed to the second face and a sixth face fixed to the third face;
- a mixer ring of type 3 (.lambda./2) located on the first face;
- a first waveguide located on the first face and connected to a first point of the outside of the mixer ring;
- a second waveguide located on the first face and connected to a second point of the outside of the mixer ring at (.lambda./2) from the first point;
- a third waveguide positioned on the fourth face;
- a first diode positioned in a first hole passing through the two dielectric layers and the conductive layer and directly connected by its cathode at a third point of the mixer ring at (.lambda./4) from the second point on one side of said point, and by its anode to the third guide;
- and
- a second diode positioned in a second hole passing through the two dielectric layers and the conductive layer and directly connected by its anode to a fourth point of the mixer ring at (.lambda./4) from the second point on the other side of said point, and by its cathode to the third guide.
