TMAV-AWSB70 Tower Mounted Amplifier Variable Gain

TMAV-AWSB70 Tower Mounted Amplifier
Variable Gain Full Band AWS TMA w/700 MHz Bypass
General Description
Westell’s 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 TMAV-AWSB70
provides filtering and uplink signal amplication for AWS while bypassing
the full 700 MHz frequency band.
With the TMAV-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. To support all types of deployment
environments, the gain for the AWS signal can be set in 1 dB increments
B90-TMAV-AWSB70
from 3 dB to 13 dB using AISG 2.0. Additionally the TMA supports
control of Smart-Bias-T RET Antennas via AISG re-injection on the
Antenna port eliminating the need for a separate AISG cable; thus
improving reliability and costs.
