Products from Dominion MicroProbes, Inc

Dominion MicroProbes, Inc. (DMPI) is a U.S.-based manufacturer of RF test probes for semiconductor measurement technology. The company was founded in 2011 by professors at the University of Virginia and has since been developing and manufacturing micromechanical waveguide test probes for the electrical characterization of RF components directly on the wafer. The focus is on measurements in the millimeter-wave and submillimeter-wave ranges, extending up to terahertz frequencies.

Select DMPI Test Probes Based on the Measurement Task

Waveguide Test Probes: For S-parameter measurements on RF semiconductor devices in defined waveguide frequency bands.
Dual-Band Test Probes: For measurements across coaxial and waveguide frequency ranges. An integrated diplexer separates the signal paths; continuous frequency sweeps require a measurement system designed for this purpose.

DMPI test probes can be used to characterize MMICs (monolithic microwave integrated circuits) and other RF semiconductor devices on the wafer. S-parameter measurements using a vector network analyzer describe the frequency-dependent reflection and transmission characteristics. The results are used, among other things, for device characterization, the creation of circuit models, and the testing of RF circuits.

What Matters When Selecting Test Probes

First, the frequency band must be suitable for the measurement task. Equally important are the contact arrangement and the GSG contact spacing of the contact areas on the wafer, as well as the mechanical mounting on the probe station. For the complete measurement setup, the vector network analyzer (VNA) and, if necessary, the frequency extension modules must also be taken into account. Especially for dual-band measurements, the test probes and measurement system must be compatible with the intended frequency sweep.
