The compact Circuit Card Assembly (CCA) to the left shows the successful result of a reverse engineering effort that provides a drop-in replacement using bare microcircuits (die) that successfully replaces an obsolete 1982 microcircuit that was built using a Bipolar Gate Array. This CCA fits in a microcircuit package that has the identical footprint to the original microcircuit. This is used by the USAF to maintain F-16 aircraft.

This 500W Power Amplifier was originally upscreened by the DoD contractor from +85°C maximum to +125°C in order to successfully meet the requirements of an F-16

As of 2013, these ICs from the OEM no longer met the requirements at +125°C due to a design change.

This microcircuit contains three small CCAs inside of a hermetically sealed package.

  • GCI performed an evaluation of the circuit and determined the root cause of the decrease in performance for the new OCM design.  


  • GCI performed a circuit modification and corrected the issue and restored the original performance at +125°C.

  • The above graph shows the pre-2013 performance, the post-2013 new OCM design performance, and the GCI retargeted circuit performance.

  • The new solution is a drop-in replacement for the prior microcircuit.
