Abstract: Systems and methods of reducing SNR and increasing bandwidth of received signals are disclosed. LNAs receive signals from an antenna via a common input matching network. The amplified signals are downconverted, filtered and digitized before being coherently combined at a DSP. Depending on the LO frequencies used by mixers in the different receiver paths, the combined signals reduce the SNR when the LO frequencies are the same by reducing the non-correlated noise introduced by the LNAs or increase the bandwidth processed when the LO frequencies are different. The bandwidths are contiguous or non-contiguous.
