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.
