Singlemode and Dual Mode 800/1900 MHz Power Distribution Unit
Time and space are important considerations when selecting and installing wireless components at base
transceiver station sites. The simple, compact design of ADC’s ClearGain Power Distribution Unit (PDU) is
intended to help service providers save both. From a compact unit that is easily mounted on a wall or a
rack, ClearGain PDUs provide power and alarming for ADC’s tower-mounted amplifiers.
Features:
Provides power and alarm functions for on-site monitoring of masthead units (MHUs)
Monitors condition of feeder cable
Wall- or rack-mountable to fit available space
LED indicators for alarm functions
Simple, compact design allows for easy installation and connections
The ClearGain PDU is an integrated unit that provides power and alarm functions for the ClearGain
TMA system. The ClearGain Singlemode PDU provides power for up to six single frequency TMAs. For
dual band systems, the ClearGain Dual Mode PDU provides power for up to six dual band TMAs or
twelve multi-frequency systems that amplify a single frequency.
The PDU monitors the current of the MHU. If an MHU fails, the ClearGain PDU gives an alarm
indication. The ClearGain PDU also monitors the condition of the feeder cable. Alarm indicators identify
failure in the feeder cable or MHUs and in which MHU the failure occurred, providing fast and easy on-
site diagnostics. The flexible design of ClearGain PDUs allows them to be rack-mounted or mounted
indoors on the wall or on the side of a BTS cabinet.
An external Bias-T unit is used in conjunction with the PDU and is designed to connect directly into the
BTS coaxial connector. Bias-T units are available with various connector types, with gas tube arrestors for
lightning protection on the ANT and MHU ports. Quarter wave stub lightning protection is integrated on
the BTS port of the Bias-T units.
