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
