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
- Lithographic thin-film construction
- Excellent crosstalk characteristics
- Non-oxidizing nickel alloy tips
- Innovative force delivery mechanism
- 40GHz, 50GHz, 67GHz, 110GHz and 145GHz connectors available
- GSG, SG, GS, GSGSG, GSSG, SGS configurations
- 50 to 250 µm pitches (other pitches available on request)
- High current version (2 A) 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 Ω on Al, <0.02Ω on Au
- Save valuable wafer space and reduce pad parasitics by being able to shrink pad geometries to 25 x 35 µ m (best case)
