Architectures for frequency-domain channelization of broadband signals

In this talk, the design of receiver architectures for channelization of broadband signals will be described. Architectures based on harmonic-reject mixers and frequency-folding will be presented. These approaches divide an input spectrum into contiguous sub-bands while minimizing the number of distinct LO sources in the receiver. Anti-aliasing requirements for these approaches, and techniques for relaxing these requirements will be presented.
