Kathrein 78210147 DTMA Radio Frequency Module

The Kathrein 78210147 is a Dual Tower Mounted Amplifier (DTMA) for UMTS base stations, specified for a receive band of 1920-1980MHz and transmit band of 2110-2170MHz, with AISG-compliant remote control and monitoring. Tower mounted amplifiers are installed at the antenna, close to the radiating element, where they boost the weak uplink signal before it travels down the feeder cable to the base station, improving the receiver’s noise figure and extending effective cell range and in-building penetration compared to amplifying only at the base station cabinet. Being AISG-compliant, this unit supports remote configuration, gain adjustment, and status monitoring over the standard Antenna Interface Standards Group protocol used across multi-vendor RF site equipment, and being a dual (12dB gain, dual-path) design it serves two antenna sectors or paths from a single unit, reducing tower-top clutter versus separate single-band amplifiers. Kathrein’s DTMA-UMTS-12-AISG series has been widely deployed across European and international UMTS/3G mobile networks. Tech-Star (UK-based, shipped worldwide) supplies tested Kathrein RF site hardware for mobile network maintenance and spares.
