Abstract: A coplanar waveguide transmission line and a design method thereof are provided. The coplanar waveguide transmission line includes a first dielectric substrate, a center conductor strip, and two ground conductor strips. The first dielectric substrate has a first surface and a second surface opposite to each other. The center conductor strip and the ground conductor strips are stacked and fixed to the first surface. The center conductor strip includes a first segment and a second segment. A width of the first segment is greater than a width of the second segment, so that the first segment and the second segment form a step structure. A rectangular groove recessed toward the second surface is defined in the first surface, and a part of the center conductor strip is stacked and fixed to a side, distal from the second surface, of the rectangular groove to form a defected ground structure.

Abstract: A passive uniplanar double-balanced star RF mixer, comprising a substantially planar support substrate with a conductive layer of material disposed on one side and a slotline and first, second, and third coplanar waveguides formed therein which are configured to accommodate different frequencies. The first waveguide is bifurcated on one end into two waveguide branches which form first and second waveguide terminations each physically coupled to one end of the slotline. The second waveguide is electrically coupled to the first waveguide at a location spaced apart from the branches. The third waveguide is electrically coupled to the slotline at a position located approximately equi-distant from the slotline ends. A first grounding element is connected to the grounds of the first and third waveguides, and is positioned adjacent to the first branch termination. A conductive surface is enclosed by the waveguide branches and the slotline. This enclosed conductive surface has its smallest planar dimension large relative to the width of the slotline. The enclosed surface is further connected to the first and second grounding element across the coplanar waveguide branches. A second grounding element is connected to the grounds for the second and third waveguides, and is positioned adjacent to the second branch termination. First and second diodes are connected by a cathode to the center conductor of the first waveguide first end termination and at an anode to the first grounding element and the enclosed conductive surface. Third and fourth diodes are connected by an anode to the center conductor of the first waveguide the second end termination and at cathodes to the second grounding element and the enclosed conductive surface.

Abstract: In some embodiments, a system may include a passive uniplanar single-balanced millimeter-wave mixer. In some embodiments, a three-port diode-tee IC forming a mixer core is coupled between an end of a slotline balun and a second coplanar balun. The operational bandwidth of a mixer structure is enhanced by optimizing the distance between the mixer diode-tee core and the back-short circuits. The frequency separation of LO and IF signals may be accomplished by means of stand-alone three-port filter-diplexer device. The system may allow wider than a frequency octave operational bandwidth for a frequency converter device all the way into millimeter wave frequencies at the same time as supporting the operational bandwidth for baseband IF signal over more than six frequency octaves. In some embodiments, the system may accomplish a 500 MHz to 34.5 GHz continuous IF bandwidth with RF signal sweeping from 33 GHz to 67 GHz and local oscillator at 67.5 GHz fixed frequency.

Abstract: A novel technique for coupling microwave signals to a slot transmission line and for effecting a simultaneous impedance transformation. One lead of a microwave capacitor, connects to a source of microwave signals via a microstrip or coplanar transmission line. The other capacitor lead, located in the same plane as the slot line, crosses the slot line at a right angle and connects to the ground plane on the other side of the slot. A short-circuited segment of the slot line extends N.lambda./4 beyond the point of crossing where N is an odd integer.

Abstract: Embodiments include waveguide launchers and connectors (WLCs), and a method of forming a WLC. The WLC has a waveguide connector with a waveguide launcher, a taper, and a slot-line signal converter; and a balun structure on the slot-line signal converter, where the taper is on the slot-line signal converter and a terminal end of the waveguide connector to form a channel and a tapered slot. The WLC may have the waveguide connector disposed on the package, and a waveguide coupled to waveguide connector. The WLC may include assembly pads and external walls of the waveguide connector electrically coupled to package. The WLC may have the balun structure convert a signal to a slot-line signal, and the waveguide launcher converts the slot-line signal to a closed waveguide mode signal, and emits the closed signal along channel and propagates the closed signal along taper slot to the waveguide coupled to waveguide connector.
