Unfolded lange coupler

WebUnfolded Lange Coupler (0200) FIG. 2 (0200) illustrates a conventional prior art microstrip unfolded Lange coupler as detailed in the text MICROWAVE ENGINEERING, by David M. Pozar, ISBN 0-201-50418-9, 1990, page 431. This structure requires one or more wire bridges or air bridges to implement the Lange coupler function. It is these bridges ... WebLange Coupler can be widely used since it readily provides a broadband 90° phase split. In comparison, the branch line coupler has a narrow bandwidth and has an inconvenient shape, which is very waste full of chip space. The advantage of this design is that we can use Lange Coupler as a combiner and 90° phase shifter thus reducing component ...
