TMAV-1900-FB Tower Mounted Amplifier
Variable Gain 1900 MHz Full Band TMA w/AISG Re-inject
General Description
Westell’s Variable Gain 1900 MHz Full Band Tower Mounted Amplifier
(TMA) with AISG Re-inject output is an ideal solution for optimizing
LTE cell site performance by improving base station receiver sensitivity.
With the TMAV-1900-FB, operators will see fewer failed connection
attempts, fewer context drops, expanded coverage area (critical for
VoLTE), and increased uplink data throughput; all in a compact, highlyreliable, and cost-effective package.
To support all types of deployment environments, the gain of the
TMAV-1900-FB can be 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 re-injection on the Antenna port eliminating the
B90-TMAV-1900-FB
need for a separate AISG cable; thus improving reliability and costs.
