MICROWAVE UP/DOWN CONVERTER

Product center
SFDC-A Series Multi-Octave Downconverter
BACK TO PREVIOUS

SFDC-A Series Multi-Octave Downconverter belongs to our microwave downconverter series that has a high performance and an octave overage by RF signal. Its frequency step is precise and accurate to 10Hz with a variety of IF and signal bandwidth choices. This series of converter is mainly used for electronic countermeasure system, radar system, and satellite communication system. Its excellent phase noise, clutter suppression, and in-band flatness data can 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-A Series Microwave Downconverter is available in both 2U and 4U sizes.

Applications: T&M Systems/Satellite Communications/MIMO
    Features & Benefits:
  • 1. Multi-octave RF coverage (0.5 ~ 67GHz) 
  • 2. 4GHz or above instantaneous signal bandwidth 
  • 3. Amplitude Equalization and Group Delay 
  • 4. Variety of commonly used IF and bandwidth combinations 
  • 5. Excellent phase noise specification (67GHz): ≤-100dBc/Hz@10KHz 
  • 6. Internal and external reference switching 
  • 7. Remote programming
