The PICOPROBE® MODEL 140, a high performance microwave probe which incorporates a WR-8 waveguide with our patented coaxial design techniques, has inherent low loss and low dispersion characteristics. Like all of our Picoprobe® microwave probes, the Model 140 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 and Ground-Signal-Ground footprints are recommended for optimum performance.
