Lange couplers are a modern miracle of microwaves. Here is the quadrature coupler at its best: low loss, wide bandwidth, compact layout, and CAD elements good to go. This coupler spawned an entire industry of wideband hybrid-style amplifiers that is still here today in spite of a lot of good competition from MMICs.

Webpling. In [7], couplers were designed in a multilayer structure with two- and three-strip couplings. These approaches rely on broadside coupling through a dielectric layer between the microstrip lines. It is also possible to use an original or unfolded Lange coupler [1, 3] for 3-dB coupling.
