Design and Optimization of Phase Change Material-Based Switches and Circuits

This presentation will cover the most recent developments in PCM technologies for microwaves at XLIM. The first part of the presentation will show optimization of coplanar waveguide integrated PM switches. Bias and layout optimization have allowed improving PCM switch off-state isolation by more than 10dB compared to basic designs. A second part will be devoted to the analysis of switch reliability for space borne applications. Finally, several RF circuits like SPDT switches and dual-band filters will be presented.
