RF Probes

Cascade Microtech created the first microwave probe in 1983 that enabled the first on-wafer 18 GHz measurements and accelerated the commercialization of gallium arsenide chips. Our line of RF probes is designed to meet the challenges of high-frequency probing and ensures low and stable contact resistance on aluminum pads.

Infinity Probe

Infinity Probe

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.

Fixed Pitch Compliant Series

Fixed Pitch Compliant Series

The FPC-Series (Fixed-Pitch Compliant) is a high frequency 50 ohm coaxial probe that offers a signal line with either one or two low-inductance fixed-pitch ground contacts. The probe tip structure is lithographically defined for unsurpassed impedance control, preserving the highest integrity possible when launching and receiving signals from SMT boards, hybrids and multi-chip modules(MCM).
