Abstract
A channelization circuit channelizes baseband signals in the channels of a wideband signal. The channelization circuit includes a phase shifter, a Fourier transform circuit, filtering circuits, commutator circuits, and a summation circuit. The phase shifter circuit is configured to receive the baseband signals. The Fourier transform circuit is coupled to the phase shifter circuit and configured to frequency translate the baseband signals to the channels of the wideband signal. The filtering circuits are coupled to the Fourier transform circuit, and the commutator circuits are coupled to the filtering circuits. The summation circuit is coupled to the commutator circuits and configured to generate the wideband signal.
