PicoProbe

Since 1980, GGB Industries, the originator of the Picoprobe® line of microwave and oscilloscope probes, has served the on-wafer probing needs of the worldwide semiconductor industry, beginning with a line of high impedance troubleshooting probes for diagnostic studies of the internal workings of complex logic and memory chips. In 1988, GGB Industries, Inc., revolutionized on-wafer microwave probing with a new patented coaxial microwave probe having 50 ohm coplanar flexible tips. The introduction of a high performance W-band millimeter wave probe in 1992 established GGB Industries, Inc., as the world leader in microwave probes. Our hallmarks are craftsmanship, precision, customer service, and problem solving.
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.
