CobaltFx Vector Network Analyzer

FEV15 FREQUENCY EXTENDER - 50 OHM

CobaltFX is anchored by a 2 or 4-Port, 9 or 20 GHz VNA. Cobalt’s high dynamic range and directivity allow for highly accurate and stable millimeter-wave S-parameter measurements. CobaltFx 15 is dedicated to the 50-75 GHz waveguide band and offers an unparalleled combination of price, performance, flexibility and size. 

Highlights: 

• Frequency range: 50-75 GHz
• Measured parameters: S_{11 ~} S₄₄
• System dynamic range: 120 dB (10 Hz IF Bandwidth)
• Measurement time per point: 10* usec typ.
• Waveguide ports: IEEE 1785-2s standard 
  *Depends on selected VNA model

The VNA 
The VNAs used in this system are from Copper Mountain Technologies’ highly advanced Cobalt Series. They feature fast sweep speeds down to 10 microseconds per point and a dynamic range of up to 152* (10 Hz IF Bandwidth) dB, all comprised in a compact, USB form factor. 

The CobaltFx 15 is compatible with the following Cobalt Series VNAs: 

VNA	Frequency	Dynamic Range	Add-Ons
C4209	9 GHz	152 dB	Frequency Extenders, Cables, Accessories
C4220	20 GHz	135 dB	Frequency Extenders, Cables, Accessories
C4409	9 GHz	152 dB	Frequency Extenders, Cables, Accessories
C4420	20 GHz	133 dB	Frequency Extenders, Cables, Accessories

The Extenders 
The extenders are packaged in small and versatile enclosures that allow for flexible port arrangements with respect to the waveguide. Waveguide ports are manufactured in accordance to the new IEEE 1785-2a standard and ensure industry best alignment and repeatability of connection, allowing for long interval times between calibration. 

Calibration Kit 
The system comes with a precision calibration kit containing flush short, offset piece and broadband load, and allows for full 12-term port calibration.
