The Keysight 85106D Millimeter-Wave Network Analyzer extends the 8510C network analyzer into the millimeter-wave spectrum, delivering vector S-parameter measurements from 33 GHz to 110 GHz. This system provides high-accuracy, error-corrected characterization of millimeter-wave components across Q-, U-, V-, and W-band waveguide configurations. TRL calibration reduces residual system uncertainties to 46–50 dB for directivity and source match, while maintaining a dynamic range of 87–75 dB and phase detector accuracy better than ±0.02 degrees.

– System Architecture
The 85106D integrates with the 8510C network analyzer through the 85105A millimeter-wave controller, which manages amplification and RF switching. Two 85104A test set modules house the waveguide hardware, splitting S-parameter measurement capability between them. The system accepts the 83621B or 83651B synthesized source as the RF stimulus.
– Typical Applications
• Millimeter-wave component testing and characterization
• High-frequency transmission-line measurements
• Waveguide filter and antenna evaluation
• Integrated-circuit and module S-parameter verification across Q-, U-, V-, and W-bands
