HD404X Upconverter
(Agile 64/256 QAM Block Upconverter)
 

The HD404X series of 64/256 QAM block upconverter cards is ideal for Video on Demand applications, due to its extremely high channel density. One HD404X system can block upconvert up to 64 channels in 2 rack units, making it the most space-effective upconverter solution on the market.

Each 2RU chassis can host up to sixteen upconverter cards. There are three different HD404X card types; the HD4041 which upconverts a single QAM channel, the HD4042 which upconverts two QAM channels to a frequency agile 12 MHz block and the HD4044 which upconverts four QAM channels to a frequency agile 24 MHz block. A chassis can support any combination of these cards.

      

Advanced design allows a single card to cover a frequency band from 85 to 860 MHz band edge and still maintain a phase noise specification that exceeds the requirements of 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.

Built-in power detectors allow for easy input and output level configuration. The controller module features a remote control interface (with optional SNMP), allowing full control and monitoring of all frequencies and levels.

This advanced, cost effective upconverter offers high performance, flexibility and unmatched space efficiency.
