Spec Sheet

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-MountedAmplifiers (TMAs) minimize the cost of network expansion and improve quality of service, allowing service providers to increase profitability from new and existing services.

The ClearGain TMAs improve signal quality by boosting the uplink signal of a mobile system to increase receiver performance and improve overall coverage.

Features:

Provides amplification of the Band

Highly advanced LNA amplifies RX signal for improved receiver performance and increase in coverage

Dual duplex feature reduces the number of feeder cable runs by providing simultaneous operation of TX and RX with low TX loss

Full Band feature provides amplification of the entire band

Advanced filtering maintains the lowest possible noise figure for improved quality of service

Slim, stackable design conserves tower space and reduces tower-relatedcosts

Seamless aluminum sleeve construction protects components from the elements

Modular system is fully compatible with all base stations

Power and alarming for up to six masthead units is provided from a single unit at the base station

Introduction

Unacceptable network quality is one of the main reasons for mobile subscriber churn. With industry churn at their current rates, a service provider’s entire customer base could be lost in as few as three years. The cost of acquiring new subscribers to replace the existing customer base can be enormous. Improvements in quality of service can directly impact a service provider’s profitability through the cost savings associated with increased subscriber retention and the additional revenue gained from increased billable minutes of use resulting from improved signal quality.

While subscribers are willing to pay a premium for data services, improved quality of service is necessary to provide new data services. Due to the tradeoff between bit rate and bandwidth inherent to data services, improved signal quality is required to achieve the same level of performance at even higher data rates. ADC’s

ClearGain Tower-MountedAmplifiers help provide this improvement in signal quality.

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 Antenna geographic area, resulting

in increased revenue.

System Overview

The ClearGain TMA system is modular, consisting of a Masthead Unit (MHU), a Power Distribution Unit (PDU) and a Bias-TUnit. This system provides full compatibility with all base stations. The ClearGain MHU offers dual duplex operation and incorporates a highly advancedfixed-gain,lownoise amplifier (LNA) andhigh-performancefilters for added reliability. The MHU amplifies each band to maximize signal quality and optimize coverage.

The ClearGain MHU features a slim, lightweight design. This allows two ClearGain TMAs to

be mounted with one set of brackets thereby, 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 is 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 rackor wall-mountedon the side of a BTS cabinet.

An external Bias-TUnit is used in conjunction with the ClearGain PDU. TheBias-Tinserts DC power onto the coaxial cable and extracts alarm and monitoring signals from the coaxial cable.

Singlemode and Dual Mode 800/1900 MHz 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 Power Distribution Unit (PDU) is intended to help service providers save both. From a compact unit that is easily mounted on a wall or a rack, ClearGain PDUs provide power and alarming for ADC’s tower-mountedamplifiers.

Features:

Provides power and alarm functions for on-sitemonitoring of masthead units (MHUs)

Monitors condition of feeder cable

Wallor rack-mountableto fit available space

LED indicators for alarm functions

Simple, compact design allows for easy installation and connections

The ClearGain PDU is an integrated unit that provides power and alarm functions for the ClearGain TMA system. The ClearGain Singlemode PDU provides power for up to six single frequency TMAs. For dual band systems, the ClearGain Dual Mode PDU provides power for up to six dual band TMAs or twelve multi-frequencysystems that amplify a single frequency.

The PDU monitors the current of the MHU. If an MHU fails, the ClearGain 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 onsite diagnostics. The flexible design of ClearGain PDUs allows them to be rack-mountedor mounted indoors on the wall or on the side of a BTS cabinet.

An external Bias-Tunit is used in conjunction with the PDU and is designed to connect directly into the BTS coaxial connector.Bias-Tunits 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 theBias-Tunits.
