Paper Abstract

We demonstrate an 80-tap radio frequency (RF) transversal filter based on a 49GHz-spacing integrated micro-comb source. By employing a record 80 micro-comb lines, or taps, for the transversal filter, we achieve very high performance including a QRF factor more than four times higher than previous results. Our experimental results match well with theory, showing that our transversal filter is a competitive solution to implement advanced adaptive RF filters with high frequency selectivity and reconfigurability, and with potentially lower cost and footprint. This approach is promising for applications in modern radar and satellite communications systems.
