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.

Air Coplanar Probe

ACP Probe

The Air Coplanar Probe is a rugged microwave probe with a compliant tip for accurate, repeatable measurements on-wafer. It features excellent probe-tip visibility and the lowest loss available. Available as both single and dual, the ACP probe combines outstanding electrical performance with precise probe mechanics and is todays most widely used microwave probe available. [View more]

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. [View more]

T-Wave Probe

T-Wave Probe

The T-Wave Probes enable wafer-level electrical measurement of mmW devices and materials up to 1.1 THz and deliver low insertion loss and low contact resistance when probing gold pads. [View more]

|Z| Probe®

|Z| Probe

The |Z| Probe® patented technology assures high-accuracy measurements with low contact resistance and superior impedance control. The RF/Microwave signal makes only one transition to the coplanar contact structure within the shielded, air-isolated probe body maintaining signal integrity over a temperature range from 10 K to 300°C.
