ClearGain

®

 Tower-Mounted Amplifiers 

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 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-related costs
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
