Since 1981, GGB Industries, Inc., has
blazed the on-chip measurement trail with
innovative designs, quality craftsmanship,
and highly reliable products. Our line of
custom microwave probe cards continues
our tradition of manufacturing exceptional
testing instruments.
For technical assistance, custom product
designs, or off-the-shelf delivery,call
GGB Industries, Inc., at (239) 643-4400.
Our patented probe structures provide the
precision and ruggedness you require for
both production and characterization
testing. And only Picoprobe offers the
lowest loss, best match, low inductance
power supplies, and current sources on a
single probe card.
(…110 GHz to be exact.)
Picoprobe elevates probe cards to a higher level…
Through unique modular design
techniques, hundreds of low frequency
probe needles and a variety of microwave
probes with operating frequencies from DC
to 40, 67, or even 110 GHz can be custom
configured to your layout.
Our proven probe card design technology
allows full visibility with inking capabil-
ity and ensures reliable contacts, even when
probing non-planar structures.
Not only do you get all the attractive
features mentioned, but you get personal,
professional service, rapid response, and
continuous product support--all at an
affordable price so your project can be
completed on time and within budget.

Protecting your radar system
just got a whole lot easier
New high power surface
mount limiters from
Aeroflex / Metelics are
making your receiver/
protector sections a whole
lot easier to design. These
drop-in devices include
11 completely integrated
components that have
been optimized for S
and C band radar systems.
In comparison to silicon
and GaAs MMICs, which
lack thermal capacity and
thermal conductivity, these
devices offer stable peak
power handling through
8 GHz.
• Frequency bands from
20 to 8000 MHz
• 100 W C.W. and 1 KW
Peak Power Handling
• Flat Leakage Power
of 20 dBm
• 8 x 5 x 2.5 mm SMT
Packaging
We’ve put our semicon-
ductor experience to work
in developing a variety of
broadband and octave
band models. Call or visit
