US : Superconductor Technologies Inc. (Nasdaq: SCON) ("STI"), the global leader in high-temperature superconducting (HTS) products for wireless voice and data applications, today announced it has received approximately $4.0 million dollars year-to-date in orders for SuperPlex(R) and AmpLink(TM) products, as part of a major wireless carrier's 3G (EV-DO) roll-out. Shipments began in March and are scheduled through the second quarter of 2005. The financial terms of the orders were not disclosed.

"Recently, there has been a significant amount of spectrum changing hands and several top-tier carriers are now putting that spectrum to use as they aggressively roll-out nationwide high-speed data networks," said Jeff Quiram, the company's president and chief executive officer. "Working proactively with major US wireless carriers and our other customers, STI has a proven capacity to help wireless operators solve their network challenges."

The SuperPlex solution provides a cost-effective way to simplify the installation of personal communication services (PCS) signals over an existing 850 megahertz (MHz) cellular network. With SuperPlex, STI offers an overlay solution that simplifies installation, improves network performance, and reduces costs of deployment. SuperPlex enables antenna and cable sharing without degrading the performance of underlying cellular networks. STI's SuperPlex product line also includes a line of 850 MHz and 1900 MHz duplexers with industry-leading insertion loss and band rejection performance.

The AmpLink solution provides duplexing and uplink enhancement for PCS base stations. AmpLink is available in both an outdoor configuration and in a compact, indoor, modular package. By integrating STI's proprietary low-loss duplexers and class-leading low noise figure low noise amplifiers (LNAs) into a single package that replaces two traditional components, a PCS duplexer and tower-mounted amplifier, the AmpLink allows wireless operators to enhance network quality and deploy fast and efficient PCS networks and overlays using "zoning-friendly" solutions.

The AmpLink and SuperPlex products have been used in rollouts of 3G data networks, such as EV-DO, to improve the link quality in both forward and reverse directions. By deploying PCS networks with AmpLink and SuperPlex, wireless operators can maximize performance of the new network while maintaining the cell spacing of their existing 850 MHz network. In addition to improving network performance, both the SuperPlex and AmpLink lower installation and operating expenses for wireless carriers deploying new voice and data services.
