ClearGain® AISG Compliant TMAs
Americas
As mobile usage continues to increase, service providers are faced
with the challenge of optimizing and expanding their wireless
networks to provide new and existing services. ADC’s ClearGain®
Tower-Mounted Amplifiers (TMAs) minimize the cost of network
expansion and improve the quality of service, allowing carriers to
increase profitability from new and existing services.
ClearGain TMAs improve signal quality by boosting the uplink (RX) signal of a mobile system
immediately after the antenna. This compensates for the loss in signal strength that occurs
when the signal is passed through the coaxial feeder cable to the base transceiver station (BTS)
at the base of the tower. These TMAs perform this amplification with the lowest possible noise
contribution, resulting in a substantial increase in receiver performance and an improvement in
overall coverage. These improvements in quality of service allow mobile subscribers to place more
calls, make longer calls, and successfully complete calls in an expanded geographic area, resulting
in increased revenue.
SPEC SHEET
ClearGain TMAs are fully AISG Compliant. Therefore, the TMA system allows for Remote Electrical
Tilt (RET) signals to be injected into the system at the BTS and extracted out of the TMA from
a special RET connector. The benefit of this system is that the carrier does not have to run RETspecific cables up the tower resulting in less wind loading, fewer components, and lower costs.
Features:
• Highly advanced LNA amplifies RX signal for
improved receiver performance and increase
in coverage
• Fully AISG Compliant
• Dual duplex feature reduces the number of
feeder cable runs by providing simultaneous
operation of TX and RX with low TX loss
• Advanced filtering maintains the lowest
possible noise figure for improved quality
of service

Introduction
TMAs improve signal quality by boosting the
uplink (RX) signal of a mobile system immediately
after the antenna. This compensates for the loss
in signal strength that occurs when the signal
is passed through the coaxial feeder cable to
the base transceiver station (BTS) at the base
of the tower. ClearGain TMAs perform this
amplification with the lowest possible noise
contribution, resulting in a substantial increase
in receiver performance and an improvement in
overall coverage. These improvements in quality
of service allow mobile subscribers to place more
calls, make longer calls, and successfully complete
calls in an expanded geographic area, resulting in
increased revenue.
The TMA system allows for RET signals to be
injected into the system at the BTS and extracted
out of the TMA from a special RET connector.
The benefit of this system is that the carrier does
not have to run RET-specific cables up the tower
resulting in less wind loading, fewer components,
and lower costs.
The ClearGain TMA system is modular, consisting
of a masthead unit (MHU), a power distribution
Tower-Mounted Amplifier
unit (PDU) and a Bias-T Unit, providing full
compatibility with all base stations.
System Overview
The ClearGain MHU offers dual duplex operation
and incorporates a highly advanced fixed-gain,
low-noise amplifier (LNA) and high performance
filters for added reliability. The MHU amplifies
the entire band to maximize signal quality and
optimize coverage.
The ClearGain MHU features a slim, lightweight
design. This a allows two ClearGain TMAs to be
mounted with one set of brackets, conserving
valuable and costly tower space and reducing
clutter on the tower. The TMA is protected with a
strong, aluminum sleeve construction designed to
ensure superior weather protection and resistance
to corrosion, resulting in increased reliability.
In the ClearGain TMA system, DC power and
RET signals are supplied to the MHU from a
ClearGain PDU. The PDU also provides alarming
and monitoring of the feeder cable and up to six
MHUs from a single unit. The flexible design of
the ClearGain PDU allows it to be rack- or wallmounted on the side of a BTS cabinet.
An external Bias-T Unit is used in conjunction
with the ClearGain PDU. The Bias-T inserts DC
power onto the coaxial cable and extracts alarm
and monitoring signals from the coaxial cable.

AISG Compliant Power Distribution Unit
Time and space are important considerations when selecting and installing wireless components at
base transceiver station sites. The simple, compact design of ADC’s ClearGain AISG Compliant Power
Distribution Unit (PDU) is intended to help service providers save both. From a compact unit that is
easily mounted on a wall or in a rack, the ClearGain PDU provides power and alarming for up to three
ClearGain Tower-Mounted Amplifiers (TMAs).
ClearGain TMAs are fully AISG Compliant. Therefore, the TMA system allows for Remote Electrical Tilt
(RET) signals to be injected into the system at the PDU and extracted out of the TMA from a special RET
connector. The benefit of this system is that the carrier does not have to run RET-specific cables up the
tower resulting in less wind loading, fewer components, and lower costs.

Features:
• Fully AISG Compliant
• Provides power and alarm functions for on-site monitoring of up to six masthead units (MHUs)
• Monitors condition of feeder cable
• Wall or rack-mountable to fit available space
• LED indicators for alarm functions
• Simple, compact design allows for easy installation and connections
The ClearGain AISG Compliant PDU is an integrated unit that provides power and alarm functions for
the ClearGain TMA system. The PDU monitors the current of the MHU. If an MHU fails, the ClearGain
AISG Compliant PDU gives an alarm indication. The ClearGain PDU also monitors the condition of the
feeder cable. Alarm indicators identify failure in the feeder cable or MHUs and in which MHU the failure
occurred, providing fast and easy on-site diagnostics.
The ClearGain TMA system allows for RET signals to be injected into the system at the BTS and
extracted out of the TMA from a special RET connector. The benefit of this system is that the carrier
does not have to run RET-specific cables up the tower resulting in less wind loading, fewer components,
and lowers costs.
The flexible design of the ClearGain AISG Compliant PDU allows it to be rack-mounted or mounted
indoors on the wall or on the side of a BTS cabinet.
An external Bias-T unit is used in conjunction with the Dual Inline PDU and is designed to connect
directly into the BTS coaxial connector. Bias-T units are available with various connector types, with
gas tube arrestors for lightning protection on the ANT and MHU ports. Quarter wave stub lightning
protection is integrated on the BTS port of the Bias-T units.
