Introduction

Satellite communication demands stable, high-quality frequency conversion for applications ranging from SCPC data links to HDTV broadcasting. SatHarbor presents the UT-4500 Series Up Converters, designed with advanced phase noise performance, wideband support, and robust gain. Whether you’re building a transportable “flyaway” system or outfitting a large earth station, the UT-4500’s compact 1RU form factor, Daisy Chain redundancy capability, and user-friendly remote control interface make it an ideal choice for modern satellite networks.

Key Features & Highlights

1. Broadband Frequency Range Options

   • Supports C-Band (multiple sub-band variants), Ku-Band, and X-Band frequencies, enabling seamless integration with diverse satellite services.

   • Step size as small as 125 kHz standard (optionally 1 kHz), ensuring precise frequency tuning for demanding carriers.

2. High Gain & Low Phase Noise

   • Standard gain of 35 dB and +10 dBm minimum output at the 1 dB compression point (Ku-Band), allowing long cable runs to modems without external amplifiers.

   • Exceeds Intelsat phase noise masks by up to 6 dB, ideal for low bit rate digital circuits and phase-sensitive demodulators.

3. Daisy Chain Redundancy Switching

   • Patented Daisy Chain design distributes switching across individual converters, removing the need for a centralized chassis.

   • Saves rack space, eliminates multiple power supplies, and reduces cabling complexity—translating to lower capital and maintenance costs.

4. Excellent Spurious & Stability

   • Carrier spurious below -65 dBc at 0 dBm output ensures minimal interference.

   • Internal references maintain ±1 x 10^-8 stability from 0 to 50°C, with optional external 5 or 10 MHz references for tighter specs.

5. Compact 1RU Design

   • At just 1.75 inches in rack height, the UT-4500 conserves valuable server room space.

   • Detachable I/O module (IOM) with user-selectable 50 or 75 Ω IF connections and standard SMA for RF output.

6. Remote Control & Management

   • EIA-232/EIA-485 interfaces plus Ethernet (Telnet, SNMP, built-in HTML GUI) for flexible monitoring and control.

   • ASCII-based commands or front-panel menu for full configuration, status retrieval, and custom integration.

Typical Applications

1. SCPC, DAMA, & TDMA Links

   • Suited for single-carrier systems, demand-assigned multiple access, and time-division networks needing stable, precise frequency conversion.

2. Full Transponder & HDTV Broadcasting

   • High linearity and low phase noise ideal for uplinking entire transponders or high-definition video feeds without compromising signal quality.

3. Transportable Flyaways & Marine Terminals

   • 1RU form factor, low power dissipation (~60 W), and robust Daisy Chain redundancy reduce the footprint in mobile or maritime deployments.

4. Large Earth Stations

   • Eliminate separate redundancy chassis and numerous cables, enabling easy scaling for multi-carrier operations.

Best Practices & Considerations

• Use Daisy Chain Redundancy: Leverage integrated switching to cut down on extra hardware costs and simplify link maintenance.

• Confirm Frequency Sub-Band: The UT-4500 offers multiple frequency variants for C-, X-, and Ku-Band operations. Verify the target satellite band and coverage range.

• Plan for External Reference: If you need ultra-tight stability or want the converter to output a 10 MHz reference to drive an external BUC or LNB, confirm the appropriate configuration.

• Mind the IF Impedance: Choose the correct 50 or 75 Ω I/O module for the IF path to match existing equipment.
