Cascade
Infinity Probe – Coaxial
High-frequency performance with low, stable contact resistance on aluminum pads
Infinity Probe - Coaxial Overview
Ideal for device characterization and modeling, Infinity probe combines extremely low contact resistance on aluminum pads with unsurpassed RF measurement accuracy for highly reliable, repeatable measurements. Proprietary thin-film and coaxial probe technology reduces unwanted couplings to nearby devices and transmission modes.
Infinity Probe - Coaxial Key Features
