The PICOPROBE MODEL 90, a high performance microwave probe which incorporates a WR-12 waveguide with our patented coaxial design techniques, has inherent low loss and low dispersion characteristics.

Like all of our Picoprobe microwave probes, the Model 90 features: individually spring loaded Beryllium-Copper tips which provide reliable contacts even when probing non-planar structures; direct viewing of probe tips for accurate positioning; and can be designed to almost any pitch and footprint. Smaller pitches (50-450 microns) and Ground-Signal-Ground footprints are recommended for optimum performance.
