A method is provided. A first enable signal is asserted so as to enable a first driver, where the first driver has a first output and a first parasitic capacitance. A second enable signal is asserted so as to enable a second driver, where the second driver has a second output and a second parasitic capacitance. The first and second outputs are coupled together by a switching network when the second driver is enabled. Pulses from complementary first and second radio frequency (RF) signals are applied to the first driver, where there is a first set of free-fly intervals between consecutive pulses from the first and second RF signals, and pulses from complementary third and fourth RF signals are applied to the second driver, wherein there is a second set of free-fly interval between consecutive pulses from the third and fourth RF signals.
