We have analyzed the response and noise-limited sensitivity of the radio-frequency single-electron transistor (RF-SET), extending the previously developed theory to the case of arbitrary large quality factor Q of the RF-SET tank circuit. It is shown that while the RF-SET response reaches the maximum at Q roughly corresponding to the impedance matching condition, the RF-SET sensitivity monotonically worsens with the increase of Q. Also, we propose a novel operation mode of the RF-SET, in which an overtone of the incident rf wave is in resonance with the tank circuit.
