Distributed Frequency Converter

Distributed Frequency Converter (DFC)

The NSI Distributed Frequency Converter is used in Panther RF systems to convert RF signals to IF signals that can be measured by the Panther receiver. The DFC design includes several improvements over alternate solutions, such as :

- Support for very long LO cables, up to 100 ft, for fundamental mixing at 18 GHz

- Test and reference LO cables can have different lengths

- Only one cable to connect each remote mixer to the LO/IF Unit

 

For systems based on network analyzer instead of the Panther receiver, adding a DFC can dramatically improve the system dynamic range. Benefits of the DFC include:

- Minimization of RF cable losses, especially at 40 and 50 GHz

- Easy interface to mm-wave modules

- No flexing of expensive high-frequency cables

 

The DFC is available as a set (LO/IF Unit plus two mixer modules) or as individual components.

One LO/IF Unit is required for each system.
