Abstract
An electronic component includes a passive device, a phase change material (PCM) switch, and an electrically insulating layer. The PCM switch is electrically connected to the passive device. The PCM switch includes a phase change material (PCM) layer, a first electrode contacting the PCM layer, a second electrode contacting the PCM layer, and a resistive heating element configured to heat a portion of the PCM layer. The electrically insulating layer is disposed between and thermally coupled to the PCM layer and the resistive heating element.
