An RF probe is a device which is used to measure RF signals in an electronic circuit. In 1980 Reed Gleason and Eric Strid invented the first high frequency wafer probe while working at Tektronix. They later went on to found Cascade Microtech in 1983. When looking for an RF Probe, there are a few key parameters that must be considered.
Frequency Support: Based on the application of the circuit, you must select a probe that operates up to the frequency at which you would like to test the circuit. RF Probes can support frequencies up to 110 GHz.
Configuration: RF Probes require at least two conductors - Signal and Ground. The way these conductors are oriented is know as the configuration. For example - You can have GS (Ground and Signal), GSG (Ground, Signal, Ground), GSSG (Ground, Signal, Signal, Ground)
Probe Pitch: This is the distance between centre of the probe tips. These vary between 50 to 1200 microns. Larger probe tips are not practical for high frequencies.
everything RF has listed RF/High Frequency probes from the leading manufacturers. Use the filters to narrow down on the probe by frequency, configuration or probe pitch. Once you find a probe that is right for you, download the datasheet or request a quotation on the product.
