Summary

Chapter ten, by Roberto Gómez-García, José-María Muñoz-Ferreras, and Manuel Sánchez-Renedo, from the University of Alcalá, Spain, is devoted to Multi-Band RF Front-Ends for Radar and Communications Applications. New concepts and implementations of radio-frequency (RF) front-ends are essential for emerging radar and wireless technologies. In this context, multi-band approaches are interesting for acquiring multi-standard services. This chapter focuses on deriving a mathematical framework for band allocation so that the minimum sub-Nyquist sampling frequency can be employed without aliasing in a digital multi-band acquisition process. This justifies the use of direct-sampling architectures for the associated receiver, where the input RF multi-band bandpass filter becomes the key element in terms of hardware. Design rules and experimental prototypes for a novel class of multi-band bandpass filter based on signal-interference principles and suitable for these systems are also described.
