MTMA-800/E900-12dB-2eNodeBport2ANTport-AISG
Model: ATADU2001 (AISG 2.0)
Product Description
   The multiband tower mounted amplifier (MTMA) is a low-noise amplifier installed near the antenna to
satisfy the co-siting purposes. It helps to improve the signal-to-noise ratio and enhance the receiving
sensibility of the BTS system. It enhances the uplink coverage and improves uplink and downlink imbalance
of the base station. It effectively reduces the transmitting power of cellphones, improves voice and data
communication quality. When scanning the AISG ALD, the MTMA can be operated from one primary
controller, either on NodeB0 or NodeB1 port. When scanning the AISG ALD, the TMA is responding to the
AISG controller with two individual serial numbers (unique IDs) with each their two subunits (two subunits per
frequency band).
Features
 High linearity and low noise performance.
 Balanced LNA design and power failure bypass for high reliability.
 Light weight and compact design.
 Designed for co-siting purposes.
 Wall mounting and mast mounting.
 Built-in lightning protection up to 10 kA.
 Support AISG 2.0 protocol.
