Offering dual duplex operation, ClearGain DD1900 Ground-Mounted Amplifier (GMA) incorporates fixed-gain, low-noise amplifier and high-performance filters. Without need for tower climbs, GMA improves signal quality by boosting uplink (RX) signal of mobile system. Amplifying full 1,900 MHz band, it consists of amplification module and power distribution unit, providing full compatibility with all base stations.

********************
The ClearGain GMA’s slim, modular, stackable design conserves rack space and is easy to install. These features minimize the cost of network expansion and improve the quality of service (QoS) that allow wireless operators to increase profitability from new and existing services.

In addition to the benefits a traditional ClearGain system provides, the ClearGain DD1900 Full Band GMA offers dual duplex operation and incorporates a highly advanced fixed-gain, low-noise amplifier (LNA) and high-performance filters for added reliability. The DD1900 Full Band GMA amplifies the full 1900 MHz band to maximize signal quality and optimize coverage.

“While subscribers are willing to pay a premium for data services, improved quality of service is necessary to provide new services,” said Bill Heuer, ClearGain product manager for ADC. “Due to the tradeoff between bit rate and bandwidth inherent to data services, improved signal quality is required in order to achieve the same level of performance at even higher data rates. With the improvement in signal quality that ADC’s ClearGain GMAs provide, customers will find significant value in this solution.”

ClearGain GMAs improve signal quality by boosting the uplink (RX) signal of a mobile system. GMAs perform this amplification with the low noise contribution, resulting in a substantial increase in receiver performance and an improvement in overall coverage. These improvements in QoS allow mobile subscribers to place more calls, make longer calls, and successfully complete calls in an expanded geographic area, resulting in increased revenue. The ClearGain GMA consists of an amplification module and a power distribution unit (PDU), providing full compatibility with all base stations.
