Features
|  |
| The GGB Industries, Inc., MODEL 40A microwave probe 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 18 db through 40 GHz. With its individually spring loaded, Beryllium-Copper, Tungsten, or Nickel 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 microwave probe 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 as well.Any pitch (tip spacing) from 25 to 2540 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.Connection to the Model 40A is through a female K connector (2.9mm) which is 3.5mm connector compatible.

| Flexible Tips for Flexible ProbingEach Model 40A has patented, independently spring loaded tips which ensure a reliable 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. A well-appreciated feature of the Model 40A is the ability to view the exact contact area which eases probe placement 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. Coaxial Transmission Improves PerformanceThe Model 40A uses a precision miniature 50 ohm coaxial cable from the probe tips to the connector interface. The coaxial design provides lower loss and less radiation than coplanar designs. The miniature coaxial cable is fabricated from flexible Beryllium-Copper which greatly improves the probe’s durability. It's sister probe, the Model 40M has the lowest insertion loss in the industry--less than 0.5db.Dual Microwave ProbeThe PICOPROBE® DUAL MICROWAVE PROBE consists of two separate probes mounted on a single holder. One probe is fixed to the holder; the other is adjustable. Each probe may be individually configured with GSG, GS, or SG footprints having any fixed pitch from 50 to 2540 microns. The probe to probe (signal to signal) spacing is user adjustable over a 4000 micron (160 mil) range. When ordering, an initial signal to signal spacing should be specified (up to .75 inches).Probe CardsModel 40A probes can be mounted on both industry standard 4.5 inch probe cards and custom-sized probe cards for testing wafers at high frequencies using standard automatic or manual probe stations. Picoprobe Probe Cards can be designed with all of our microwave probes operating from 40, 67, and 110 GHz for RF applications and can be combined with multiple DC needles for power and low frequency signals as well.Multi-Contact WedgesOur unique Multi-Contact Wedge designs accommodate multiple RF and DC contacts on a single, compact adapter. This compact design provides the user with a convenient method for testing wafers at high frequencies using standard automatic or manual probe stations. The user can choose from a variety of wiring options for the DC or power needles and select any combination of 40, 50, 67, and/or 110 GHz RF probes. |

An Entire Line of Microwave Probes
Other models of RF probes are available with standard tip spacings of up to 2540 microns. Larger tip spacings are available as well. For special applications, the Model 40A 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 above 40 GHz, GGB Industries, Inc., offers a complete line of microwave probes operating up to 1100 GHz (Model 1100). 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, WR-3 for 220 to 325 GHz, WR-2.2 for 325 to 500 GHz, and WR-1 for 750 to 1100 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 INFORMATIONWhen ordering Picoprobe Model 40A probes, use the following part numbering convention: Model 40A-configuration - pitch - mounting styleConfiguration: 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 40A-GSG-150-P is a Model 40A with Ground, Signal, Ground configuration with 150 microns between each contact mounted in a P style adaptor.
