The GGB Industries Model 67A probe sets new standards in microwave probing performance. Using low loss coaxial techniques, the Model 67A achieves an insertion loss of less than 1.1 db and a return loss of greater than 14 db through 67 GHz
With its individually spring loaded, Beryllium-Copper tips, the Model 67A 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 67A also provides direct viewing of the probe tips for accurate positioning.
The Model 67A can be mounted in various adaptors for use with standard microwave probe stations. Custom mounts are available.
Each Model 67A has patented, independently spring loaded tips which make contact to the probing surface. Because the tips are flexible they minimize circuit damage, increase probe life, and most importantly, provide a reliable individually spring loaded contact for each point. With a small amount of overdrive, the point scrubs the surface to make a reliable contact free of dust, dirt, and oxide contamination. The ability to view the exact contact area eases probe positioning and allows for the precise positioning necessary for good LRM calibrations. The flexible tips even allow probing of non-planar surfaces such as ceramic substrates and laser diode structures.
