Selecom 117630D/0082 DDTMA dual-duplexed tower-mounted amplifier tuned to the GSM900 uplink band (890-915MHz).

The Selecom 117630D/0082 is a DDTMA (Dual-Duplexed Tower-Mounted Amplifier) built by Selecom for the GSM900 band, covering the 890-915MHz uplink range used by GSM900 mobile networks. Mounted at the antenna on the tower, it combines the duplexing filter and low-noise amplifier for a sector’s transmit and receive paths in one tower-top housing, amplifying the weak uplink signal from handsets before feeder-cable attenuation degrades it on the way down to the base station. This lifts effective receiver sensitivity and coverage on GSM900 sectors, particularly where long feeder runs would otherwise eat into the RF budget. Dual-duplexed TMAs tuned to the 890-915MHz uplink band were widely deployed by GSM900 operators during network build-out and coverage optimisation, and many remain in service supporting legacy 2G and shared 2G/3G sites. Tech-Star (UK-based, shipped worldwide) stocks tested tower-mounted amplifiers and RF site hardware for GSM900 networks.
