Overview

 

CCI’s Dual Band (Cellular/PCS) TMA contains  two TMA’s (i.e.  one TMA for each band) in a dual housing.  The TMA is full band and fully duplexed.  High linearity improves the uplink sensitivity and the receive performance of base stations.  The TMA is fully compliant with the latest AISG 2.0 specification.  The TMA supports all 2G, 3G and 4G (Cellular/PCS) systems.  It provides a convenient package for sites upgraded to dual band or quad antenna configurations.  The dual housing  package reduces tower loading, leasing, and installation costs.  Unit count on the tower is cut in half.  An excellent match for two branch receive diversity applications using dual polarization antennas.  The input and output connectors are located inline for ease of installation in space constrained areas such as uni-pole structures and stealth antennas.

 

Technical Description:

The TMA system consists of an outdoor dual band tower mount unit which combines separate PCS and Cellular  antennas onto a single BTS port.  Both the Cellular and PCS paths are dual duplexed to separate the low-power uplink signals from the high-power downlink signals at the antenna port, amplify the low-level uplink signals using ultra-low noise amplifiers (LNA’s), and recombines all four paths at the BTS port.  The tower mount units consist of six band-pass filters, two redundant low-noise amplifiers, bypass failure circuitry, and bias tee’s which are all housed in an IP65 moisture proof enclosure, with IP68 Immersion proof connectors suited to long-life masthead mounting.  The unit provides protection against lightning strikes via a multi-stage surge protection circuit.  AISG 2.0 DC power and control is provided via the feeder cable from the BTS using the AISG 2.0 and 3GPP standard.  Additionally the AISG TMA operates at constant power when powered by an AISG 2.0 Compatible Site Control Unit, but may be powered by a “Standard Power distribution Unit.  A separate AISG connector is also provided to allow direct AISG connection or “Daisy Chaining” to multiple AISG products at the top of the tower.
An optional indoor site control unit (SCU) is available to power up to up to 32 AISG modules per sector and to provide the all the monitoring and alarm functions for the system.  The SCU is housed in a single (1U) 1.75” x 19” rack and contains dual redundant power supplies capable of being “hot swapped” that provide a regulated DC supply voltage on the RF coax for the tower mount amplifiers.
