UCD4940
256 QAM Upconverter

The VCom UCD4940 up-converter/down-converter is designed for use with the VCom TR700 subscriber transceiver and PA700 power amplifier in UHF fixed broadband wireless applications. The UCD4940 combines an agile 256 QAM up-converter and a 16 QAM down-converter in a 19" 1RU chassis.

When combined with the PA700 and DPX700, the system forms a complete high power transmitter chain and low noise receive chain for direct connection to the base station antenna and DOCSISTM - compatible Cable Modem Termination System. Full control of the unit (and the PA700 if connected), including input/output frequency and level is accomplished via the front panel buttons and liquid crystal display. The UCD4940 and PA700 are also remotely manageable over a serial RS232/RS485 connection or future optional SNMP. Status and alarm data can also be viewed either from the front panel or remotely. The UCD4940 offers a quick and easy installation as a base station IDU for BWINTM based on DOCSISTM.

  • 53 to 858 MHz agile up-converter with performance that exceeds the requirements for 256 QAM
  • High up-converter output power 256 QAM +61 dBmV (+12 dBm); fully DOCSISTM compliant
