Display Status:

This object is on display in the James S. McDonnell Space Hangar room at Steven F. Udvar-Hazy Center in Chantilly, VA.

Collection Item Summary:

This artifact is a signal processing device designed for use in the first generation of Milstar military communications satellites.

To meet weight and space constraints on the spacecraft, the design achieved complex function in a small size by the use of layering. Beneath the visible surface of electrical devices and connections are three additional conducting layers (and six non-conducting layers). The buried conducting layers provide additional pathways for connecting the electrical devices on the hybrid's top layer. The completed hybrid is an ingenious puzzle in which nearly one hundred chips and devices are integrated through more than onel thousand connections. The gold-colored wire pins on the sides of the case connect the hybrid to a circuit board or electronic device.

This design represented the state of the art in miniaturization for such hybrids as of the late 1980s and early 1990s. Lockheed Martin donated this artifact to the Museum in 1998.
