CCI’s DAS Interface Conditioner module provides a single integrated connection point between a DAS system and multiple base stations. Its unique architecture interfaces with almost any MIMO or SIMO configuration. Each module can support up to two TX/RX BTS inputs. The DAS Interface module’s TX output (to DAS) is available from either of two ports so that one port can be used for monitoring of the Tx signal, and the other for feeding the DAS. The module’s Tx output ports are offset by 20dB so that a single unit can be used for both high input power and low input power DAS systems. Each Rx input from the DAS has a test port available on the module for independent monitoring of the DAS Rx signal. Independent leveling controls for each TX and RX input provide a simple way to control multiple inputs/outputs, significantly reducing link balance setup time. Base stations are connected with normal output power levels directly to the DAS Interface Module without the need to pre-attenuate power, preventing accidental overloads. The DAS conditioner module provides integrated high power attenuation for each channel with an adjustment range of up to 30 dB in 1 dB increments for both TX and Rx paths. It is a completely passive unit, with high rejection low PIM filters, requiring no external power, thus providing high reliability in a single compact design. Standard unit has Simplex output to DAS System, but optional Duplex output is available. Note that any unused TX/RX, TX Out (to DAS) or RX In (from DAS) ports must be terminated with loads rated for the appropriate ports power rating.
