Photo of upgraded Correlator 1st Down Converter (C1DC) unit. This upgrade consisted of increasing the intermediate frequency (IF) signal bandwidth from 4-6 GHz to 4-16 GHz while maintaining the current function of the existing legacy correlator. The upgrade is visible as the rectangular metal plate near the bottom center of the photo. The upgrade consisted of two wide-band amplifiers, power divider, and filter along with a cooling fan.
