Investigation of on-state power handling dependence on number of cycles for germanium telluride RF switches

RF Power-Handling Performance for Direct Actuation of Germanium Telluride Switches

“…Hence, it can be seen that the maximum power handling of the series switch at OFF-state, corresponding to amorphous GeTe, is function of the square of its width and is proportional to its thickness. As in [20], when the cross sectional area of the GeTe is reduced, the maximum power handling is also reduced.…”

“…A thermoelectric modeling of the proposed device has been performed to check by simulation the validity of (10) and (11) extracted from RF measurements based on a limited number of devices. As the failure is caused by too high a temperature in the GeTe [20], a thermoelectric modeling allows to connect RF excitation with the internal temperature of the structure. A 2D multi-physics simulator, COMSOL, has been used to simulate the GeTe switch.…”
