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 and 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/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
