SuperPlex®
Antenna sharing without compromise

For zoning friendly installations, thousands of cell sites around the world use STI's SuperPlex® line of premium multiplexers. Designed for fast, cost-effective deployment, HighQ Duplexers, Triplexers, and all STI multiplexers reduce the need for additional antennas and coaxial cable feed lines.

The STI HighQ Duplexers and SuperPlex 1-1900 triplexer provide superior multiplexing functionality in both the 850MHz cellular band and the 1900MHz PCS band. These products provide very low transmit and receive insertion loss while providing excellent cross-band isolation. This result: more transmit power delivered to your antenna and higher sensitivity to your customer's handset signals - all with the zoning-friendly convenience of one less antenna.

STI transmit filtering solutions prevent noise emissions problems at Nextel 900 receive. For cellular B-band wireless operators with excess emitted noise at 896MHz, use of STI transmit filters alleviates all noise issues. Low-loss filter design combined with high-rejection ensures optimal network performance without any noise problems. Choose from STI's stand-alone transmit filter, TXF850B , with >72dB of rejection at 896MHz, or STI's newest filter, the ETR-Duplexer for Enhanced Transmit Rejection. STI transmit filters are designed to work with any infrastructure, CDMA, GSM, TDMA, or AMPS front-end power amps and OEM duplexers.
