A planar triply-balanced microstrip mixer for microwave and millimeter wave operation includes an RF port, and IF port and an LO port. The mixer is constructed on a single side of a two-sided substrate. The single side of the substrate supports an RF balun network connected to the RF port, an IF balun network connected to the IF port, and an LO balun network connected to the LO port; a pair of crossover diode ring quad circuits arranged in a planar back-to-back configuration; and a planar microstrip feed network connecting the RF, IF, and LO ports to the diode ring quad circuits through the RF, IF and LO balun networks.read more

Resistive planar star double-balanced mixer
TL;DR: In this paper, a passive uniplanar double-balanced star RF mixer is proposed, 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.

Stripline feed for a microstrip array of patch elements with teardrop shaped probes
TL;DR: In this paper, the probe capacitance required is controlled by the maximum diameter for the teardrop shaped probe, which can be empirically determined for the operating frequency, and the shape of the probe is not critical.
