HEARING DEVICE HAVING DUAL BAND RADIO USING IMAGE FREQUENCY

A hearing device includes: a wireless communication unit configured for receiving an antenna signal carrying information in a first frequency band having a first centre frequency, and information in a second frequency band having a second centre frequency; wherein the wireless communication unit comprises: a local oscillator configured to provide a local oscillator signal; a mixer configured to receive the local oscillator signal and mixing the antenna signal with the local oscillator signal, the mixer providing an output signal; and an IF filter configured to receive the output signal; wherein an IF centre frequency associated with the IF filter is equal to a fraction of a difference between the second centre frequency and the first centre frequency; and wherein a local oscillator frequency associated with the local oscillator is equal to a difference between the second centre frequency and the IF centre frequency.
