Abstract
An impedance matching apparatus for providing impedance matching for an RF component. The apparatus includes a balun transformer circuit having a primary coil at an input side of the balun transformer circuit. The primary coil can be connected to a signal source to receive an input signal from the signal source. The balun transformer circuit further includes a secondary coil at an output side of the balun transformer circuit, the secondary coil being coupled to the primary coil to supply an output signal to the RF component and having a parasitic leakage inductance configured to match the output impedance of the signal source to the input impedance of the RF component
