A power circuit includes a RF transistor and an input match network coupled to an input to the RF transistor and to an input to the power circuit. The input match network includes a resistor, an inductor and a first capacitor coupled together in series between the input to the RF transistor and a ground, and a second capacitor coupled in parallel with at least the resistor. The value of the second capacitor is selected so that the resistor is bypassed over at least a portion of the high frequency range of the power circuit.
