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. Benefits: • Small size and low weight. Allows for easy installation with minimal visual impact and in weight-restricted implementations. • Improved uplink coverage. TMAs enable base stations to receive mobile signals more clearly in a wider coverage area than could otherwise be achieved. • Increased RF performance. By improving signal quality and/or reducing mobile phone power transmission, TMAs provide more successful call attempts, a reduction in dropped calls, maximized data rate, improved call quality and the extension of handset battery life. • Fully AISG compliant.

The inline feature also allows for easier connection of the jumper cables to the antenna. A ClearGain TMA system is modular, consisting of both a masthead unit (MHU) and a power distribution unit (PDU), providing full compatibility with all base stations. Due to its exposed installation, the TMA is designed to withstand demanding weather conditions and features lightning protection, fault monitoring, and a fail-safe bypass circuitry system. + - INpUt NO cOM Nc ALARM MhU DIScONNect power Distribution Unit MhU1 MhU2 MhU3 Base Station tower- Mounted Amplifier Bias-t BtS 2w w w . a d c . c o m • + 1 9 5 2 9 3 8 8 0 8 0 • 1 8 0 0 3 6 6 3 8 9 1 8/ 07 • 105188AE ClearGainDualInlineTMAs ClearGain® Dual Inline TMAs Americas AWS Dual Inline Typical Specifications ELECTRICAL Nominal Impedance of RF Inputs and Outputs: 50 Ohm Frequency Range TX: 2110 – 2155MHz RX: 1710 – 1755MHz Passband (RX) Gain: 12db Noise Figure: .1.4dB Dynamic Range: Input at 1 DB Gain Compression: +13dBm 0utput IP3: +25dBm Bypass Insertion Loss: .2.0dB Isolation in Tx Path: >50dB Insertion Loss of TX Path (TX to ANT): 0.5dB Passband Return Loss Tx Band: 18dB Rx Band: 18dB Rx Rejection in Tx Band: >75dB PHYSICAL Dimensions (HxWxD): 210 mm x 166 mm x 81 mm Weight: 4.5kg Housing: Aluminium CONNECTORS Antenna Connector: 7/16 DIN Female...
