1.9 GHz Integrated Balun Probe
2.4 GHz Integrated Balun Probe


This is an example of a 900 MHz Integrated Balun Probe.

It incorporates a 50 ohm unbalanced to 200 ohm balanced differential transformer.

The probe can be built with or without a center tapped ground needle and

may also incorporate DC bias through the differential pair or via separate needle contacts.
Other performance features include: individually spring loaded Beryllium-Copper or optional Tungsten tips which provide reliable contacts even when probing non-planar structures;direct viewing of probe tips for accurate positioning;and can be designed to almost any pitch and footprint.Please contact our office for additional information regarding other differential probe designs.
