Overview
In this paper, we review the potential applications of single-walled carbon nanotubes in three areas: passives (interconnects), actives (transistors), and antennas. In the area of actives, potential applications include transistors for RF and microwave amplifiers, mixers, detectors, and filters. We review the experimental state of the art, and present the theoretical predictions (where available) for ultimate device performance. In addition, we discuss fundamental parameters such as dc resistance as a function of length for individual, single-walled carbon nanotubes.

1. Introduction
The development of carbon nanotube synthesis, both for single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs), and of nanotube device physics has been rapid in the previous decade. The sphere of potential applications is broad due to their superior mechanical, thermal, and electrical properties. These have been reviewed in several recent monographs[1 7], as well as other manuscripts in this volume. However, an intriguing sphere of application which has until recently received relatively minor attention is in the area of high speed (RF, microwave, mm-wave, and THz) electronics. At first glance, the idea of combining nanotechnology with RF circuitry may seem to be a rather poor match, due to the typically high impedance of nano-electronics devices. However, the intrinsic speed limit of carbon nanotube devices can be very high, up to the THz range, so that on further reflection it seems potentially...
