DUAL4040D Upconverter
(Dual Frequency Agile 64/256 QAM Upconverter)
 

The DUAL4040D is a fully agile commercial quality dual IF upconverter for data over cable and digital video-on-demand applications. Advanced design allows the DUAL4040D to cover a frequency band from 53 to 858 MHz and still maintain a phase noise specification which exceeds the DOCSIS requirements for 64/256 QAM. Remarkably low out of band noise performance and low spurious are achieved through high level mixing, a microwave frequency IF and multiple levels of filtering.

     

The DUAL4040D is fully DOCSIS compliant and optimized for 256 QAM cable modem traffic. Built in IF & RF power detectors allow for easy input and output level configuration. The remote control interface allows full control and monitoring of all frequencies and levels. This advanced, cost effective upconverter offers high performance, flexibility and space efficiency.
