Chapter 1 Introduction

Jens Timmermann and Thomas Zwick

This book concentrates on UWB RF systems. In the analog RF frontend, a high relative bandwidth and not necessarily a high absolute bandwidth poses new challenges to the RF system design. We are therefore concentrating on the lower frequency range of around 1–10 GHz where a large variety of system concepts are under investigation worldwide. A short list of typical applications envisioned by researchers and companies is:

  • high data rate, short range applications: typically portable devices and built into antenna systems in consumer electronics or into access point infrastructure
  • low data rate, wider range, eventually combined with a ranging application: small portable devices (also wearable ...
