Abstract :
In this communication, double heterostructure GaAs/GaAlAs MMIC microstrip and coplanar strips structures are studied over the 2-18 GHz band, for their use as travelling wave electrooptic modulators. The obtained theoretical and experimental results show that the coplanar strips configuration, under odd mode excitation, presents less insertion losses and quite less dispersion in comparison to the microstrip structure.
