WESTELL.COM General Description Westell’s Twin Tower Mounted Amplifier (TTMA) with AISG Re-inject output is an ideal solution for optimizing LTE cell site performance by improving base station receiver sensitivity (for both the 700 MHz and 850 MHz frequency bands). With the TTMA-700850 product series, operators will see improved service performance levels — fewer failed connection attempts, fewer drops, expanded coverage area (critical for VoLTE), and increased uplink data throughput — all in a compact, highly-reliable, and cost-effective twin package that supports one full sector. To support all types of deployment environments, the gain of the TTMA- 700850 can be set in 1 dB increments from 3 dB to 13 dB, using an AISG 2.0 interface connection (either external connector or RF AISG commands from the base station via the BTS-1 port only). Additionally, the TMA supports control of Smart-Bias-T RET Antennas via AISG re-injection on the Antenna port, thus eliminating the need for a separate AISG cable and improving reliability and costs.

General DescriptionWestell’s Twin Tower Mounted Amplifier (TTMA) with AISG Re-inject

output is an ideal solution for optimizing LTE cell site performance by

improving base station receiver sensitivity (for both the 700 MHz and 850

MHz frequency bands). With the TTMA-700850 product series, operators

will see improved service performance levels — fewer failed connection

attempts, fewer drops, expanded coverage area (critical for VoLTE), and

increased uplink data throughput — all in a compact, highly-reliable, and

cost-effective twin package that supports one full sector.

To support all types of deployment environments, the gain of the TTMA-

700850 can be set in 1 dB increments from 3 dB to 13 dB, using an AISG

2.0 interface connection (either external connector or RF AISG commands

from the base station via the BTS-1 port only). Additionally, the TMA

supports control of Smart-Bias-T RET Antennas via AISG re-injection on

the Antenna port, thus eliminating the need for a separate AISG cable and

improving reliability and costs.

Features & Benefits

• Advanced, balanced LNA design amplifies both the 700 MHz

and 850 MHz bands (uplink)

• Variable Gain 3-13 dB (with 1 dB steps)

• Automatic LNA bypass ensures network availability

• Superior performance with one of the lowest noise figures in

the industry: < 1.7 dB at 13 dB gain

• High receive isolation: > 80 dB

• High reliability and performance

• Supports AISG 2.0

• AISG re-injection on the Antenna Port for control of Smart-

Bias-T RET Antennas - eliminates the need for a separate

cable (model -01 and -11 ONLY)

• Separate external AISG connector for control of non-Smart-

Bias-T RET Antennas

• Includes AISG 2.0 remote software download

• Twin TMA supports one full sector in a single enclosure

• Easy upgrade or swap with our A90-700C (no lease impact to

add 850 MHz frequency band)

• Similar size and weight to a single band Twin TMA
