Selecom 117630D-0069 DDTMA dual-duplexed tower-mounted amplifier for GSM base station uplink coverage improvement.

The Selecom 117630D-0069 is a DDTMA (Dual-Duplexed Tower-Mounted Amplifier) manufactured by Selecom for GSM base station sites. Mounted at the top of the tower close to the antenna, a dual-duplexed TMA combines the duplexing filter and low-noise amplifier for a sector’s transmit and receive paths in a single tower-top unit, boosting the weak uplink signal from mobile handsets before feeder-cable losses degrade it on the way down to the base station. This improves receiver sensitivity and effective cell coverage, and is particularly valuable on sites with long feeder runs or challenging RF budgets. Dual-duplexed TMAs of this type were a standard tool used by mobile operators during 2G/GSM network build-out and densification to extend coverage without adding new sites, and they remain in active service on many legacy and rural base stations today. Tech-Star (UK-based, shipped worldwide) stocks tested tower-mounted amplifiers and RF site hardware.
