We report electrical measurements of the radio frequency response of carbon nanotube field-effect transistors (CNFETs). The very low current drive of CNFETs makes conventional high-frequency measurements difficult. To overcome this problem, we have used a novel approach to easily measure the response up to 250 MHz in nonoptimized experimental conditions. We observe a clear response of our CNFETs with no deterioration in signal up to at least 250 MHz, which is the limit for our present configuration.
