Overview
The 9900 Series Frequency Converters are designed for advanced satellite communication systems, offering a wide range of frequency plans. These converters feature optimized phase noise, amplitude flatness, and spurious outputs to provide transparent frequency conversion for video and data applications.
Features
The converters support expandable NSU 1:N Switchover Series (D-323), amplitude slope adjust, and three monitor and control ports:
- RS485/RS422 remote interface (JGA)
- RS485/RS422 control interface (J7) for NSU redundancy system (D-323) or alternative interface
- 10/100Base-T Ethernet interface (J6B)
Additional features include RF, IF, and LO monitor ports, automatic switching to external 5/10 MHz reference, and electronic adjustment of internal reference frequency.
Specifications
The converters offer a range of specifications, including:
- Frequency step size: kHz
- Frequency sense: No inversion
- Input characteristics: 75 ohms, 60 ohms (Option 15)
- Return loss: 26 dB minimum (70 +20 MHz), 21 dB minimum (140 +40 MHz)
