GSM/CDMA duplex amplifiers
Andrew Corp has debuted three new dual-duplex tower mounted amplifiers (TMAs) for GSM and CDMA networks.
The TMAs support full band 60-MHz PCS1900, sub-band 300MHz PCS1900 and 800-MHz cellular A and B bands, improving uplink performance to enhance coverage and capacity throughout a GSM or CDMA network. The amplifiers can withstand demanding outdoor environments, the company said, with a compact and self-contained maintenance-free housing, which protects them even in severe weather or corrosive environments.
“Mobile phone subscribers expect their wireless services to connect calls on the first try every time. Too many missed or dropped calls, and they may start looking for another provider,” says John DeSana, Andrew’s group president of cable and filter products. “Andrew has the solution with tower mounted amplifiers that boost coverage where signals are weak, reduce call interference and extend a subscriber’s talk time by requiring lower handset output.”
Andrew will demonstrate the amplifiers and exhibit a wide range of products at CommunicAsia2004.
