TTMAV-700C Tower Mounted Amplifier Twin Variable Gain

TTMAV-700C Tower Mounted Amplifier
Twin Variable Gain 700 MHz Upper-C w/AISG Re-inject
General Description
Westell’s Twin Variable Gain 700 MHz Upper-C 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 TTMAV-700C, 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, highly-reliable, and cost-effective package that supports one
full sector.
To support all types of deployment environments, the gain of the
TTMAV-700C can be set in 1 dB increments from 3 dB to 13 dB, using
B90-TTMAV-700C
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.
