SFDC-C Series Microwave Downconverter

SFUC-C Series Microwave Downconverter is a broadband frequency converter that is dedicated for satellite communication. It has a high performance, high reliability and an octave covered by RF signal. Its frequency step is precise and accurate to 1Hz with a variety of IF and signal bandwidth choices. It is equipped with functions like self-testing and combination alarm which is suitable for long-time uninterrupted use, guaranteed safety and reliability. This microwave downconverter is mainly designed for satellite communication system, signal monitoring system, and electronic countermeasure system with an excellent phase noise, clutter suppression, and in-band flatness data. It is able to provide a transparent RF transmission channel to all videos or data communications. All programming commands can be set through a local panel or through network remotely. SPUC-C Series Microwave Downconverter has a standard 2U size.
