Abstract
The propagation of short picosecond pulses in coupled strip lines with a phase velocity ratio of odd and even modes of 3:1 is considered. The feature of the separation of the input pulse between the three output ports without significant loss of energy due to reflection from the input in transdirectional couplers based on coupled strip lines is experimentally shown. As a result of the analysis, it was found that the spectral components of the pulse are separating between the ports of the transdirectional coupler.

Keywords
striplines, unbalanced coupling, transdirectional coupler, pulsed action, pulse propagation, spectral characteristics.
