GGB Picoprobe Model 40A High Performance Microwave Probes
The GGB Industries Model 40A microwave Picoprobe gives an insertion loss of less than 0.8 db and a return loss of greater than 18 db through 40 GHz. With its individually spring loaded Beryllium-Copper or optional Tungsten tips, the Model 40A provides reliable contacts, even when probing non-planar structures. Available in any pitch (tip spacing) from 50 to 1250 microns. The probe can be configured with Ground-Signal-Ground (G,S,G), Ground-Signal (G,S), or Signal-Ground (S,G) tip footprints.

The GGB Industries, Inc., Model 40A Picoprobe sets new standards in microwave probing performance. Using low loss coaxial techniques, the Model 40A achieves an insertion loss of less than 0.8 db and a return loss of greater than 18db through 40 GHz.
With its individually spring loaded Beryllium-Copper or optional Tungsten tips, the Model 40A provides reliable contacts, even when probing non-planar structures. This reliable low resistance contact is one of the keys to providing highly repeatable measurements. The Model 40A also provides direct viewing of the probe tips for accurate positioning. The Model 40A can be mounted in various adaptors for use with standard microwave probe stations or attached to thin blades for use with dc probe needles on a probe card or multi-contact wedge. Custom mounts are available.
Any pitch (tip spacing) from 50 to 1250 microns may be specified. Probe pitches greater than 1250 microns can be accommodated. The probe can be configured with Ground-Signal-Ground (G,S,G), Ground-Signal (G,S), or Signal-Ground (S,G) tip footprints. We recommend smaller pitches with a G,S,G footprint for best performance.
