Abstract
A hearing aid comprising a wireless transceiver () having an inductive antenna () and a trimming capacitor () with at least two parallel signal paths, wherein at least one of said signal paths comprises a first capacitor (), a second capacitor () and a switching transistor () arranged such that the switching transistor () is coupled in parallel with said first capacitor () and coupled in series with said second capacitor (), whereby the voltage drop across the switching transistor (), when the switching transistor is set to off, will be lower than the voltage applied across the trimming capacitor () due to voltage division between said first capacitor () and said second capacitor (). The invention also provides a method of fitting a wireless transceiver () for a hearing aid.
