Model 67A

A coplanar probe with patented flexible tips, the MODEL 67A microwave 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 or optional Tungsten tips, the Picoprobe® Model 67A microwave probe 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.

Any pitch (tip spacing) from 25 to 1250 microns may be specified. 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 results.

Line of Microwave Probes

An entire line of microwave probes are available with standard tip spacings of up to 2540 microns. Larger tip spacings are available as well. For special applications, the Model 67A can be mounted in custom adaptors, the coaxial line can be bent to fit tight spaces, ａnd the tips can be configured to match extremely non-planar surfaces or non-symmetrically placed grounds.

Other options include:
Tungsten or Nickel probe tips; 
high temperature ａnd high power versions; 
custom "chip" probes which have integrated series, parallel or termination components built into the signal tip.

For applications below 40 GHz, GGB Industries, Inc., offers the Model 40A Picoprobe which uses the 2.9mm K connector. The Model 40A performs up to 40 GHz with less than 0.8 db insertion loss ａnd return loss of greater than 18 db.

For applications above 50 GHz, GGB Industries, Inc., offers a complete line of microwave probes operating up to 325 GHz (Model 325). Several models are available with wave guide inputs: WR-22 for 33 to 50 GHz, WR-15 for 50 to 75 GHz, WR-12 for 60 to 90 GHz, WR-10 for 75 to 120 GHz, WR-8 for 90 to 140 GHz, WR-5 for 140 to 220 GHz, ａnd WR-3 for 325 GHz. The wave guide probes have an optional integral Bias T for active device measurements.  Many other types ａnd custom designs are available, so please call with your special application requirements.

ORDERING INFORMATION

When ordering Model 67A probes, use the following part numbering convention:

Model 67A - configuration - pitch - mounting style

ORDERING INFORMATION When ordering Picoprobe Model 40A probes, use the following part numbering convention: Configuration: Specify GSG, GS or SG for tip placement where S is the signal tip ａnd G is a ground tip. Use the following diagram to determine the appropriate configuration.  Pitch: Specify ground (G) to signal (S) tip spacing in Microns from 50 to 1250 microns. For standard GSG probes, the two spacings are equal. Contact the factory for spacings larger than 1250 microns or unusual tip placement ａnd spacings.

Mounting Style: Choose from thirteen adapter styles. Specify T, C, GR, P, DP, EDP, LP, Q, F, S, DS, VP, or RVP. Choose the appropriate mounting type for your application. The P, DP, EDP, LP, Q, S, DS, VP, ａnd RVP styles have the connector pointing back at a 45 degree angle to give more working area above the probe. The DP, EDP, DS, VP, ａnd RVP styles are used where extra clearance beneath the probe is needed. When using DP, EDP, ａnd DS style probes, probe positioning is more difficult due to the increased probing angle since the probe points slide further forward for a given change in the Z axis than our other style probes. Custom mounting styles are available 

Example:A 67A-GSG-150-P is a Model 67A with Ground, Signal, Ground configuration with 150 microns between each contact mounted in a P style adaptor.
