  We report a broadband RF channelizer based on an integrated optical frequency
Kerr micro-comb source, with an RF channelizing bandwidth of 90 GHz, a high RF
spectral slice resolution of 1.04 GHz, and experimentally verify the RF
performance up to 19 GHz. This approach to realizing RF channelizers offers
reduced complexity, size, and potential cost for a wide range of applications
to microwave signal detection.
