Comtech EF Data DT-4572 High Performance X-Band Downconverter

DT-4572 X-Band Downconverter System

The Comtech DT-4572 High Performance X-Band Downconverter offers extremely low phase noise, high gain and high stability characteristics. Comtech DT-4572 High Performance X-Band Downconverter also incorporates Comtech integrated redundancy switching technology which make the DT4572 an ideal solution for SCPC, DAMA, and TDMA, as well as full transponder HDTV and analog TV. 7.9-8.4 Ghz .

High Gain 

The DT-4572 has +20 dBm minimum output level at the 1 dB compression point and 45 dB of gain as a standard. This capability permits longer cable runs to the modem rack or compensates for elaborate splitting networks without adding expensive options such as external line amplifiers.

Extremely Low Phase Noise

The phase noise performance of the DT-4572 exceeds the Intelsat phase noise mask for IBS and IDR services by more than 9 dB. This allows phase dependent demodulators to perform better. The close-in phase noise is very low, making the converter ideal for low bit rate digital circuits such as those used in DAMA hub earth stations.

Daisy Chain Redundancy Switching

The converter uses our patented "Daisy Chain” integrated switching technology. The Daisy Chain design removes the relays associated with a centralized protection switch tray and distributes them across the individual converters. Daisy Chain technology successfully eliminates a central switching chassis, two power supplies, a microprocessor, and several long, costly cables. Widely accepted in the industry, CEFD’s Daisy Chain provides both pricing and marketing advantages.

Minimum Rack Space

Due to its small rack height (1.75 inches) and the elimination of the space penalty paid for a separate 1+N switch chassis, the DT-4572 and the Daisy Chain switch architecture provide the most compact and cost effective converter subsystem available. The units are ideal for the construction of transportable systems such as “flyaways,” and high capacity earth stations where space utilization and economy are prime considerations.
