Superconductor Technologies Inc. (STI) is engaged in developing and commercializing high temperature superconductor (HTS) materials and related technologies. It has commercialized wireless products using its technology and are focusing its efforts on this technology in superconducting power applications, radio frequency (RF) filters and cryocoolers. Its revenue comes from the design, manufacture, and sale of high performance infrastructure products for wireless communication applications. It has three product lines all of which relate to wireless base stations: SuperLink, AmpLink and SuperPlex. SuperLink is a compact and reliable receiver front-end HTS wireless filter system to eliminate out-of-band interference for wireless base stations, combining filters with a cryogenic cooler and a cooled low-noise amplifier. Its AmpLink is a ground-mounted unit for wireless base stations that includes a amplifier and up to six dual duplexers.
