General DescriptionWestell’s Twin Variable Gain Dual Band AWS/PCS Tower Mounted
Amplifier (TMA) is an ideal solution for optimizing LTE cell site
performance by improving base station receiver sensitivity. With
the TTMAV-AWSPCS, operators will see 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. The TTMAV-AWSPCS provides full band
operation for both the AWS and PCS bands, and with its diplexed BTS
port, it’s ideal for sites where feeder cables are shared.
To support all types of deployment environments, the gain for each
frequency band on the TTMAV-AWSPCS can be independently
adjusted from 3 dB to 13 dB in 1 dB increments using AISG 2.0. AISG
connectors allow operators to control RET antennas via a daisy-chain
cable from the TMA to the antenna, thus improving reliability and
reducing cabling costs.
