ABSTRACT:
A system includes an input multi-level channelizer, an output multi-level channelizer, and more than one amplifiers connected between the input and output channelizers. The input and output channelizers cover an operating frequency band. Each level of the input multi-level channelizer comprises a plurality of input channels, which may be bandpass filters, and may be grouped into input sub-channelizers. Each successive level of the input multi-level channelizer is configured to divide the incoming signals into smaller frequency bands. Each level of the output multi-level channelizer comprises a plurality of output channels, which may be bandpass filters, and may be grouped into output sub-channelizers. Each successive level of the output multi-level channelizer is configured to combine the incoming signals into larger frequency bands. The signal output from the output multi-level channelizer represents a filtered version of the signal input into the input multi-level channelizer.
