Integrated ultra-wideband hardware for MIMO sensing using pn-sequence approach

Abstract

The article deals with SiGe based hardware for new, flexible ultra-wideband MIMO sensing purposes using pn-sequence approach. Introduced hardware serves as future platform for scientific investigations in the complex field of ultrawideband (UWB) applications. We discuss the design aspects and prototype evaluation of the single chip M-sequence based sensor head as well as realization particularities of the transmit- and receive-front-ends for applications with direct contact measurements. The front-ends are small antenna units with active customized baluns.
