An electronic driver circuitry for an RF switch diode D1 used in Acoustic Ink Jet Printing (AIP) systems that compensates and cancels out undesired variations and non-idealities is disclosed. The electronic driver circuitry consists of a second RF switch diode D2 used as a compensation diode that is placed in close physical proximity to the RF switch diode D1 used for RF switching. To compensate for undesirable variations in the RF switch diode D1, the driver circuitry is designed such that the current in the RF switch diode D2 is adjusted in an opposite direction to cancel the unwanted variations of the RF switch diode D1.
