ASIAA NTU PHYSCorrelator System Design• Correlator Module:

– Lessons learned from 16-lag prototype:• Responsivity of >1500 Vrms/W is acceptable• Large amplitude and phase variations prevent us

from performing transformation for spectrum recovery

• Lag spacing of 12.5 psec is too small by a factor of 2

– New 4-lag Correlator module:• Spec (version 080102A) captures desired

performance goals:– amplitude </= 3.0 dBpp (2-18 GHz)– phase </= 30 deg pp (2-18 GHz)– Responsivity >/= 80Vrms/W for module,

corresponds to >/= 2000Vrms/W at mixers• Utilizes same double-balanced mixers• 6 dB pad added to mixer input ports to absorb

reflections• Lag spacing has been corrected to 25 psec• Shorter delay lines allow more space for meander

lines (less inter-coupling)
