Broadband Measurements to 220 GHz

VectorStar ME7838G 70 kHz to 220 GHz Single Sweep VNA Measurements and On-Wafer Calibrations

• Miniature mmWave MA25400A NLTL module connects directly to probes without cables for best dynamic range and stability
• MPI TITAN Probes available in 50, 75, and 100 um pitch
• Probes are field replaceable

On-wafer calibrations:

• SOLT up 40 or 70 GHz if standards provide required performance
• LRM, ALRM, LRRM, and multiline TRL up to 220 GHz
• SOLR when thru is not 0 length, is not well matched, insertion loss is less known, and there is no .s2p file describing the thru

Calibration substrates:

• Available from MPI
• When possible, use a ceramic chuck to minimize the potential for multimode parasitic propagation.
• Alternatively, use an isolation wafer on metal chuck if available
