The Comtech EF Data Model UT-4505 Up Converter is the ultimate in high performance and cost effective C-Band frequency conversion. The UT-4505 can be used for SCPC,
DAMA and TDMA as well as full transponder HDTV and
analog TV. Spectral purity, stability, group delay
characteristics fully meet or exceed the requirements of all
domestic, international, and regional commercial satellite
networks. Wideband units are available.
The UT-4505/X has +17 dBm minimum output level at the 1 dB
compression point and 35 dB of gain as a standard. These
standard capabilities permits longer cable runs to the high power
amplifier or compensates for elaborate combining networks without
adding expensive options such as external line amplifiers.
LOW PHASE NOISE
The phase noise performance of the UT-4505/X 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
Daisy Chain Redundancy Switching
The converter 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. CEFD was awarded patent
5,666,646 on this distributed protection switch topology.
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.
