GSM900 Dual Duplex TMA
The tower mounted amplifiers fromAndrew Corporation optimize networkperformance and represent the idealsolution for coverage and capacityenhancement.
By improving uplink performance, theTMAs ensure optimum coverage of fringeareas, weak spots, and indoor locations.The unit is easy to install in any wirelesssystem and guarantees:
Improved sensitivity, by reducing droppedcalls and failed connection attempts;
Enhanced signal quality, by improvingvoice clarity and data transmissionspeed;
Lower handset output, by extending talk-time, reducing interference while increas-ing traffic capacity in CDMA systems.
The GSM900 TMA is part of AndrewTMA platform, a complete range ofsuperior TMA products incorporatingstate-of-the-art technology and efficientproduction methods. The self-contained packaging isengineered to ensure the highest reliability in severe environments whilefeaturing a very compact size andattractive appearance.The GSM900 TMA includes polemounting hardware.
• AMPS rejection to help eliminate interference from nearby 800 MHzcellular transmitters. Featured in10 MHz model.
• Failsafe LNA bypass supports soft degradation in case of power failure
• Lightning protection, thanks to a built-in multi-stage surge suppressor.
