We have fabricated an aluminium single-electron transistor (SET) and characterized it at frequencies up to 8 MHz by measuring the reflected signal from a 331 MHz resonant tank in which the transistor is embedded. Within a bandwidth of 8 MHz, we measured the charge sensitivity of this radio-frequency SET, i.e. rf-SET, to 6.3×10-6 e/(Hz)1/2, which corresponds to the uncoupled energy sensitivity of 13hbar.
