Abstract
Design details for a 1-GHz bandwidth analog continuum cross-correlator for the Owens Valley Millimeter Array are presented. The correlator uses a pair of microwave mixers fed in phase quadrature to realize a complex multiplier for each baseline in the array. Very fast 180° phase switching is included to reject spurious signals
