Abstract

The embodiment of the invention relates to a switching device, a method for operating the switching device and a method for manufacturing the switching device. An apparatus is provided comprising a phase change switch (15) and a memory (14) configured to store a target state of the phase change switch. The controller (13) is configured to determine a phase state of the phase change switch and to control the heater (11) of the phase change switch to change the state of the phase change switch to a target state if the state of the phase change switch does not correspond to the target state.

Description

technical field [0001] The present application relates to switchgear and methods for operating and manufacturing switchgear. Background technique [0002] According to the 5G standard, technical requirements for radio frequency (RF) applications using high frequencies, such as radar sensing and mobile communications, are increasing. In particular, switches with improved characteristics compared to state-of-the-art CMOS switches will need to meet future demands. Phase change switches are considered promising candidates for switching RF signals. Such phase change switches use phase change materials (PCMs), which generally exhibit higher electrical conductivity in the crystalline state than in the amorphous state. By changing the phase state of a phase change material, switching devices comprising such materials can be turned on or off. [0003] For example, in order to change the phase state from an amorphous state to a crystalline state, a heater is typically used to heat ...
