Abstract
A match network with switchable variable capacitance. In one embodiment, a match network includes a first variable capacitance, a second variable capacitance, and a third variable capacitance dynamically connectable in parallel with the first variable capacitance. The match network also includes a controller configured to: control at least one of the first variable capacitance and the second variable capacitance for impedance tuning for a first power pulse; place, in response to a second power pulse, the third variable capacitance to be in parallel with the first variable capacitance; and control at least the third variable capacitance for impedance tuning for the second power pulse.
