Description:
The MA4040D is a fully agile commercial quality IF upconverter for data over cable and cable modem applications. Advanced design allows a single MA4040D card to cover a frequency band from 53-857 MHz and still maintain a phase noise specification which exceeds the DOCSIS 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.
The MA4040D is a modular circuit card designed for use with the VCom MA4000 Series. Each MA4002D card chassis with common MA4011D power supply can contain up to 10 MA4040D independent frequency agile upconverters in a 4U rack mount configuration. The redundancy features of this product make it suitable for the most demanding applications. Built-in 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.
