We review recent work on broadband RF channelizers based on integrated optical frequency Kerr micro-combs com-bined with passive micro-ring resonator filters,with microcombs having channel spacings of 200 and 49 GHz.This approach to realizing RF channelizers offers reduced complexity,size,and potential cost for a wide range of applications to microwave sig-nal detection.
