In addition to the famous line of low capacitance, high impediance Picoprobe
active probes,
GGB Industries also manufactures the highest quality, highest performing,
and most complete line of RF signal microwave probes available. They are
durable, cost effective, and available in a wide range of frequencies.
Products include G-S-G microwave probes in 40 GHz, 50 GHz, 67 GHz, 75 GHz,
120 GHz, 220 GHz, Dual Probes with two 40 GHz or 67 GHz probe heads in one mounting
(with user adjustable spacing between the two heads), multi-contact wedge
probes with mixed DC and RF probes in one head (made to customer's spec),
microwave probe cards with mixed DC and RF probes (made to customer's spec),
and calibration substrates.
