TTMAV-AWSB70 Tower Mounted Amplifier TwinVariable

TTMAV-AWSB70 Tower Mounted Amplifier
TwinVariable Gain Full Band AWS w/700 MHz Bypass
General Description
Westell’s Twin Variable Gain Full Band AWS Tower Mounted Amplifier
(TMA) with 700 MHz bypass is a cost-effectve solution for optimizing
LTE cell site performance by improving base station receiver sensitivity.
Ideal for shared feeder cable deployments, the TTMAV-AWSB70
provides filtering and uplink signal amplication for AWS while bypassing
the full 700 MHz frequency band.
With the TTMAV-AWSB70, operators will see fewer failed connection
attempts, fewer context drops, expanded coverage area (critical for
VoLTE), and increased ulink data throughput; all in an ultra-compact,
and highly-reliable package that supports one full sector. To support all
types of deployment environments, the gain for the AWS signal can be
B90-TTMAV-AWSB70
set in 1 dB increments from 3 dB to 13 dB using AISG 2.0. Additionally
the TMA supports control of Smart-Bias-T RET Antennas via AISG reinjection on the Antenna port eliminating the need for a separate AISG
cable; thus improving reliability and costs.
