WebMay 22, 2024 · 5.8.4 The Lange Coupler. A directional coupler comprised of two parallel microstrip lines cannot achieve a coupling of \(3\text{ dB}\), which corresponds to splitting the power of a traveling wave into two equal components. Lange [8] introduced a coupler, now known as the Lange coupler, in 1969. WebThe Lange Coupler is a four-port interdigitated structure originally developed by Dr. Julius Lange in 1969.

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. This design concept is based on using WebWithout the crossover, a four line coupler is called an “Unfolded Lange.”xivAccording to the literature and my Sonnet simulations, bandwidths of about an octave are easily attainable. …
