SANTA BARBARA, Calif.-Superconductor Technologies Inc. introduced its SuperFilter family of receiver filter subsystems.
The SuperFilter offers advantages over conventional filter technologies in the areas of interference protection, range extension and subsystem size for cellular and personal communications services networks, said STI.
“Wireless customers have identified the SuperFilter as the industry’s first practical superconductor subsystem,” said James Simmons, Jr., vice president of marketing and sales for STI. “The family of products incorporates the smallest, most power-efficient and lowest maintenance cryocooler with advanced radio frequency design and HTS material technologies to make the promised benefits of superconductivity commercially usable. Our tower mount platform is the only HTS filtering subsystem that can be mounted entirely on the antenna tower.”
The SuperFilter Advanced Mobile Phone Service/B product line resolves one of the most critical problems facing urban cellular operators today, said the company. Managing interference requires enormous file cabinet-sized conventional filters, which make up to 30 percent of the volume of the entire base station. The SuperFilter AMPS/B reduces the receiver filter size by 75 percent or more, while minimizing interference. This allows significantly more voice channels to be added to space-constrained cell sites in capacity-limited urban areas, said STI.
The SuperFilter Tower Mount PCS, D-, E- and F-product line offers more base station coverage area by providing ultra-low noise figures, said the company. Its HTS filter and optimized, cryocooled low noise amplifier provides operators with a cell site size reduction of up to 30 percent, while minimizing interference and offering a wide dynamic range, the company said.
