We have probed the electrical properties of top-gated single-walled carbon nanotube
transistors at frequencies up to 50 GHz by using the device as a microwave mixer. We find
that the amplitude of the mixing signal decays as a function of frequency with a characteristic
time constant that is limited by the setup. Despite the setup-limited cutoff frequency of∼ 10
GHz, we show that the devices still operate faster than 50 GHz.
