Infinity Probe

High-frequency performance with low, stable contact resistance on aluminum pads

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.

Features

Lithographic thin-film construction
Excellent crosstalk characteristics
Non-oxidizing nickel alloy tips
Innovative force delivery mechanism
40 to 220 GHz versions
GSG, SG, GS, GSGSG, GSSG configurations
50 to 250 µ m pitches
High current version (2 amp) available

Advantages

Superior field confinement reduces unwanted couplings to nearby devices and transmission modes
Superior measurement accuracy and repeatability
Small scrub minimizes damage to aluminum pad
Typical contact resistance < 0. 05 Ohm
Save valuable wafer space and reduce pad parasitics by being able to shrink pad geometries to 50 x 50 µ m

Dual Infinity Probe

The Infinity Probe® family is expanding with the addition of the Dual Infinity Probe series to 67 GHz. The new probe provides the best isolation among currently available commercial probes between the two signals. This is a critical advantage in performing accurate two or four-port calibrations. The Dual Infinity Probe is available in GSGSG, GSSG and SGS configurations and frequencies up to 67 GHz. View more ...
