Cascade
T-Wave Probe
Wafer-level electrical measurement of mmW devices and materials up to 1.1 THz
T-Wave Probe Overview
Industry-leading performance for on-wafer measurement of millimeter and submillimeter wavelength devices. The T-Wave Probes set the industry performance standard for characterization of mmWave devices. This probe delivers low insertion loss and low contact resistance when probing gold pads. Excellent tip visibility. Ability to characterize 1.1 THz devices. Typical Insertion loss < 1.5 dB between 140 GHz and 220 GHz. Integrated DC bias-T with low-profile GPPO connector.
T-Wave Probe Key Features
- Low insertion loss
- Low contact resistance
- 140 GHz – 1.1 THz versions
- Probe pitch as narrow as 25 μm
- Lithographically-defined probe tip
- Nickel contacts
