ABSTRACT:
A transitioning microstrip circulator. A Y-shaped circulator having two ps coupled to a first planar substrate and a third port coupled to a second planar substrate. The first and second planar substrates are substantially parallel and have the circulator sandwiched between them. The circulator selectively directs a millimeter wave signal along a millimeter wave transmission line to a selected port. Thereby, a signal can be coupled to circuit elements placed on each substrate. Circuit elements placed on the first and second substrate are stacked one on top of the other. This permits design flexibility and smaller packages for electronic devices.
