Comtech EF Data UT-4518 DBS-Band RF UpConverter
Ultimate in high-performance and cost effective Ku-Band and DBS-Band Frequency Conversion
UT-4518 DBS-Band RF UpConverter
The Comtech UT-4518 DBS-Band RF UpConverter is a high-performance and cost effective DBS-Band and Ku-Band frequency converter. The UT-4518 series converter can be used for applications such as: SCPC, DAMA, and TDMA, as well as full transponder HDTV and analog TV.
Another great feature of the UT-4518 DBS-Band Up Converter is that it uses CEFD's proprietary "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.
High Gain
The UT-4518 has +10 dBm minimum output level at the 1 dB compression point and 35 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.
Low Phase Noise
The phase noise performance of the UT-4518 exceeds the Intelsat phase noise mask for IBS and IDR services by more than 6 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.
