New THz-frequency contact probing for cryogenic applications from Lake Shore

Lake Shore have released details of their new THz-frequency contact probes. Compatible with Lake Shore’s CPX, CPX-VF, CRX-4K, and CRX-VF cryogenic probe station systems, the THz arm offers:

  • Precise on-wafer contact THz probing of millimetre wave devicesTHzProbeArm_4
  • New measurement possibilities for next-generation electronics
  • THz probes can be combined with standard DC/RF/microwave probe arms
  • Features a low-loss THz waveguide
  • Supports vector network analysers (VNAs) with suitable frequency extenders
  • Enables calibrated S-parameter and other hf electrical measurements at cryogenic temperatures and in magnetic fields

Signal deterioration at frequencies above 75 GHz has limited high-frequency contact measurement of electronic devices at room temperature, let alone cryogenic ones. Now Lake Shore’s breakthrough technology of a specially developed low-loss THz-frequency waveguide delivers excellent signal integrity over longer distances, at lower temperatures, and with superior arm mobility. All without interefering with the other probes in the system.
