RF SWITCH SELECTIVELY REGULATING RF ENERGY TRANSMISSION

摘要

Provided are radio frequency electromagnetic energy switches and processes of regulating the transmission of RF energy, that for the first time successfully employ a ChG PCM as a RF switching material. An inventive switch includes: a substrate; a first radio frequency energy conductive element on the substrate; a second radio frequency energy conductive element on the substrate; and a switch element on the substrate and connecting the first conductive element to the second conductive element, the switch element including a switching material; the switching material including a chalcogenide compound switchable between a first radio frequency electromagnetic energy conductivity value and a second radio frequency electromagnetic energy conductivity value by application of an activation energy to the switching material, such that radio frequency electromagnetic energy flowing in the first conductive element is either reflected off the switching material or transmitted through the switching material to the second conductive element.
