Summary:A beamforming system includes a plurality of channelizers and a channel switching module in signal communication with the channelizers. Each channelizer is configured to receive a respective input radio frequency signal and to generate a plurality of respective channels in response to downsampling the respective input radio frequency signal. The channel switching module includes a channel combining circuit configured to selectively combine a common channel generated by each channelizer to form at least one steered analog beam.
