Diplexer in 50-Ω technique for the joint generation of duobinary, bipolar and modified duobinary Gbit/s signals

Analyzing the properties of a broadband diplexer circuit in delay line technique a low cost device is derived capable of the generation of duobinary, bipolar and modified duobinary Gbit/s signals. Comparing with an equivalent circuit the restriction on 50-Ω lines allows a smaller footprint and a more versatile application when the design frequencies are to be altered.
