A hearing aid includes a signal path having an input transducer, a processor and an output transducer, the hearing aid further including a radio frequency receiver, where the receiver includes a single crystal oscillator providing a single oscillator frequency and where means are provided for generating a further number of receiving frequencies by transforming the oscillator frequency to the desired receiving frequencies. The hearing aid and the RF receiver may be separate or integrated. The invention further relates to a separate element comprising a RF receiver, the separate element being adapted for mounting on a hearing aid.
