Impedance Standard Substrates (ISSs)
  • Impedance Standard Substrates (ISSs)

Impedance Standard Substrates (ISSs) supports all of your high-frequency probing applications. Using them ensures greater accuracy and better repeatability in on-wafer calibration of vector network analyzers. Our ISSs offer the proven accuracy of LRRM calibrations with automatic load inductance compensation.
